Best Commercial Battery Backpack Blower

The Tool Box Buzz Crew seeks to crown the best commercial-grade battery backpack blower in this most recent Head-to-Head comparison test. In 2023 our crew tested and chose the best Handheld Cordless Blower. Building on that success, we are now examining battery backpack blowers. However, this Head-to-Head will primarily be geared towards commercial users. Backpack blowers are synonymous with the landscaping and property maintenance trades. We aim to determine which blowers are ready to keep up with demanding commercial use and provide the best options for pros looking to purchase a battery-powered model.

Are Battery Blowers Ready for Prime-time?

The demand for rugged, commercial-grade, battery-powered OPE is constantly growing. This demand is being fueled by technological improvements as well as legislative requirements. As of June 2024, more than one hundred cities in the United States, and the entire state of California, have banned or restricted the use of gas-powered leaf blowers. Contractors are now forced to look for battery-powered options to stay in business. These restrictions have forced OPE companies to step up their game.

Direct Comparison to Gas Powered

One common question with all battery OPE is how the tools perform compared to traditional gas-powered models. While gas vs. battery is not a true even comparison, we elected to include a gas-powered model in some of our testing to provide an additional data point. The gas-powered model will not be included in any of our rankings, but we felt the information collected is of interest.

Echo provided a sample of their model PB-770T X Series backpack blower. This blower features a 63.3 CC professional-grade two-stroke engine. This is Echo’s smallest commercial-grade backpack blower and is a close comparison to our battery-powered options in terms of power and output. Its technical specifications are as follows:

• Max Air Volume: 756 CFM
• Max Air Speed: 234 MPH
• Max Blowing Force: 33
• Fuel Capacity: 68.3 Fl./Ozs.
• Warranty: 2 Year Commercial

Best Commercial Battery Backpack Blower  | Test Criteria

We selected eight categories to determine our best commercial battery backpack blower of 2024. The tools were ranked in each category and an overall score was later used to determine our winner. The evaluation categories are:

• Measured Maximum Air Speed (MPH)
• Calculated Maximum Air Volume (CFM)
• Total Run-time on a Battery Charge (Minutes)
• Power Sled Performance Test
• Measured Noise Output (Decibels)
• Assembled Weight
• Features and Ergonomics
• Price

In addition to our overall winner, we selected a tool as our Best Value. This category highlights a single backpack blower that may not be our top-performing tool but offers an excellent overall value based on its features and performance compared to its price.

Battery Backpack Blower Lineup

Once our testing criteria were finalized, we identified the current available pro-grade models. Invitations were sent to the manufacturers to participate in our Head-To-Head. A total of six companies agreed to participate and provided us with samples of their products. Not every company that was invited chose to participate however our sample size is an excellent representation of the pro-user market.

Our participating companies provided us with the backpack blower unit, a battery, and a charger. Additionally, manufacturers were invited to include any accessories or optional parts that improve the overall user experience. Only one company elected to do this. Stihl provided us with an upgraded waist belt to enhance user comfort.

Backpack Blower Battery Systems

Determining the best battery backpack blower requires testing tools with the largest battery packs available. We requested each manufacturer provide us with the largest battery pack(s) currently available for their platform and the corresponding charger system. As a result, our charging stations look much different than in previous H2H tests! To provide performance and run-time comparable to gas-powered blowers, the battery models we tested rely upon either a large suitcase-style battery or a combination of smaller packs. Here is a breakdown of the batteries and chargers we used.

Echo

The Echo DPB-5800T is powered by any combination of up to three 56V batteries. While the kit version of this tool features two 5.0 Ah eFORCE batteries, we tested the tool with three 8.0 Ah batteries. We have a full review article of the Echo backpack blower available here. Additionally, Echo provided us with an eFORCE Rapid Charger to use during testing. The rapid charger will completely charge an 8.0 Ah battery in about 60 minutes.

Greenworks Commercial

The Greenworks Commercial model accepts two 82V batteries. The tool is capable of operating on a single battery. The tool will draw from both batteries simultaneously when two are inserted. We used two 8.0 Ah batteries, the standard offering in the kit configuration for this tool. The GWC batteries feature Bluetooth connectivity and digital display screens indicating charge levels. The charger tested is the dual port rapid charger. It is capable of charging two 8.0 Ah batteries in about one hour.

Husqvarna

The Husqvarna BLi950X battery is a large suitcase-style battery, as previously mentioned. It is a 36V, 31.1 Ah, behemoth! The 550iBTX backpack blower is only compatible with this style of battery pack. However, the battery is cross-compatible with all Husqvarna handheld 36V tools. The battery includes a standalone backpack frame for carrying when in use with handheld equipment. It also includes an adapter plug which is compatible with all Husqvarna chargers. We used a QC500 charger during testing. A full recharge of the BLi950X is approximately three hours.

Kress

The Kress Commercial Cyber System of batteries offers a variety of solutions. We tested the blower with the larger 60V CyberPack battery which is 11.0 Ahs. However, the Kress blower is also compatible with any 60V CyberPack battery, such as the smaller 4.0 Ah battery pictured above, borrowed from a Kress 16″ chainsaw. The graphene cores of the Kress batteries and the high-output Kress chargers allow a full recharge of the large suitcase-style battery in approximately ten minutes. This is an astoundingly short time compared to the other tools tested.

Milwaukee

The Milwaukee M18 FUEL battery platform is a staple of the tool industry. The kit option of their backpack blower includes a total of four 12.0 Ah M18 FUEL batteries. There are four battery ports on the blower and a minimum of two batteries must be inserted to run the tool. Each pair of batteries is drained simultaneously. It will then automatically switch to the second pair of batteries if all four batteries are inserted. We used the Milwaukee backpack blower with all four batteries inserted during testing. The kit option includes two dual-port Milwaukee Rapid Chargers. These chargers will charge two 12.0 Ah packs in about two hours.

Stihl

The Stihl AR3000L battery is the largest battery we tested. It features 41.20 Ahs on Stihl’s 36V battery platform. This large suitcase-style battery is also compatible with all Stihl handheld equipment with an adapter cable. A backpack-style platform is also available for the battery. We used a Stihl AP Adapter to connect the battery to an AL 500 high-speed battery charger during testing. The total recharge time is about three and a half hours using this combination.  Stihl recently announced their new ADA 1000 battery adapter. It allows two smaller AP series battery packs to power a large output tool like the BGA300 backpack blower—an outstanding accessory for any pro user currently on the Stihl AP battery platform.

Pitot Tube Performance Testing

To flush out generous marketing specifications from true performance for each of our tools, we employed a pitot tube test rig. This test is a specialty of Tool Box Buzz Crew member Jeff Deitz. Jeff, also a helicopter pilot, explained that a pitot tube probe measures the pressure difference of an air stream and can calculate fluid flow velocity. The Pitot Tube was invented by a French engineer, Henri Pitot, in the early 18th century.

Pitot tubes are widely used to determine the airspeed of aircraft, the water speed of boats, and the flow velocity of liquids, air, and gasses in various industries.

When manufacturers test their blowers to come up with the MPH and CFM values they follow an American National Standard (ANSI) procedure to measure the force or thrust. This is effectively an electronic scale that measures the force in Newton’s 5 inches from the blower nozzle. You can read more about the theory behind our pitot tube test rig in our Best Cordless Blower 2023 H2H article.

The Pitot Tube was set up 5 inches from each blower in the center of the air stream. Batteries were fully charged and measurements were taken at max speed setting. The data was collected at a 1 Hz sample rate or once per second for five minutes for the first test. Our second test is another five-minute recording, with the battery depleted to 25% charge.

An ExTech HD350 Pitot Tube Anemometer was used to perform this test.

Max Air Speed Winner – Greenworks Commercial

The Greenworks blower produces airspeeds over 176 MPH. We are unable to determine the exact speed because our testing monitor maxes out at 176 MPH! This is another remarkable performance for the big green machine. In second place is Stihl at 160.7 MPH. An interesting data point is that the Stihl produced slightly higher numbers on the second test run with the battery depleted down to 25%  charge. The BGA300 automatically downshifts its battery system to normalize output and performance regardless of charge charge level.

Measured MPH Results

Third place went to Echo at 150 MPH, fourth place Husqvarna at 137.5 MPH and fifth place went to Kress at 137.3 MPH. Milwaukee was our bottom finisher at 117 MPH.

Max Air Volume Winner – Kress

Using the data collected from our ExTech HD350 meter we were able to calculate the max airflow for each tool in cubic feet per minute (CFM). The Greenworks Commercial blower is the only tool that maxed out our anemometer. Therefore we added a value for Greenworks in our calculations of 200 MPH. This is a close representation of the actual value based on the tool’s performance in all of our testing. Greenworks claims that the max CFM on the tool is 225 MPH.

Calculated CFM Results

Kress is our first-place winner for air volume with a max calculated CFM of 808.44. The Kress has the largest nozzle diameter of all of the tools tested at 3.5″. This allows the Kress to move a massive volume of air. In second place we have Greenworks at 779.70 CFM. Greenworks utilizes a smaller diameter nozzle than Kress but has faster airspeed. This combination of factors still results in an impressive amount of air moved.

In third place is Milwaukee at 548.39 CFM, fourth place is Husqvarna at 545.09 CFM, and fifth place is Stihl at 531.47. Our sixth-place finisher is Echo at 220.48 CFM. This surprised our crew given that Echo performed so well in the airspeed (MPH) test. However, the Echo nozzle chokes down to 1.75″ diameter which is half the size of the Kress. Echo favors speed, but a wider nozzle would likely improve CFM output.

Max Run-time Winner-Stihl

Run-time is one of the most discussed and important categories we evaluated with our backpack blowers. Commercial users require a tool that will accomplish most tasks without constantly switching or recharging batteries. We tracked the total run-time on our blowers by combining our five-minute intervals with the pitot tube along with the time spent depleting the batteries completely. All of this was done at the highest power output setting of each tool. Fall cleanup season is quickly approaching and our entire test crew agreed that we all default to the highest setting on our blowers for tasks like this.

Measured Runtime Results

Our winner here is Stihl with a total run-time of 45:23. The crew expected nothing less from the Stihl, considering the monster 41.20 Ah battery pack that was included with the BGA300. Second place went to Echo with a total run-time of 41:15. The three large 8.0 Ah batteries used with the Echo made this a close race with Stihl.

Third place went to Husqvarna at 39:41, fourth place to Greenworks at 38:36, and fifth place to Milwaukee at 25:45. Kress came in sixth place at 19:51, which is less than half of our top two finishers. However, Kress’ lightning-fast recharge times are somewhat of a redeeming quality compared to the short run-time.

Power Sled Test | Winner-Greenworks Commercial

When life gives you backpack blowers, you build a rocket ship! In our previous handheld blower H2H, the crew used a weighted sled to test the total blowing force of the tools. This time we stepped up the test rig to accommodate our larger and more powerful commercial backpack blowers.

The testing site we used for the day provided us with access to some heavy equipment. A twenty-foot-long Hud-Son firewood conveyor was used as a ramp. We set the conveyor at a seven-degree angle with the help of a PTO hitch on a tractor. Then a classic Radio Flyer wagon was used as our test vehicle. We added a large galvanized washtub to the wagon to act as an air collector. This is a textbook example of Swamp Yankee engineering.

With the test rig in position at the bottom of the ramp, our operator held the end of the blower nozzle in line with the edge of the test rig. The operator then activated the tool on the highest output setting and held it for ten seconds. If the sled moved, we recorded the distance traveled using a tape measure on the conveyor belt. Our unloaded sled weighed in at 34.76 pounds.

All of our tools were able to move the unloaded sled. We then added five pounds to the sled (39.76 Pounds) and continued testing. Two of our blowers were completely unphased by the five-pound increase, while the others showed significant struggle. We then worked up to a fifteen-pound weight (49.76 Pounds) with the two strongest performers and repeated the test.

Power Sled Results

Greenworks is our strongest performing tool, driving the fifteen-pound loaded sled to a distance of 13.25 feet and holding steadily. Kress is our second-place finisher driving the same fifteen-pound loaded sled a total distance of 12.17 feet. Both of these blowers greatly impressed our crew during this test. Both had near-instant spooling-up to power and moving the sled. It felt as though the sled began moving as soon as the control was engaged, regardless of the weight.

Power Sled Results

Milwaukee finished in third place driving the five-pound loaded sled a total of 13 feet. Echo and Stihl were also able to drive the five-pound loaded sled. However, Husqvarna was unable to move this sled and maxed out during the unloaded test.

The overall power of a back blower is dependent upon a combination of features like nozzle diameter, maximum airspeed, and the volume of force the tool puts out. Each of our blowers has its own secret sauce approach to creating power. The Power Sled rig is an excellent visual representation of these different approaches. The stats we listed above, such as MPH and CFM, are shown in actual use with the sled. Overall, the tools with larger nozzle diameters and faster airspeeds performed best, such as our top two tools Greenworks and Kress. Conversely, blowers with fast airspeeds and narrow nozzles, such as Echo, struggled to perform well in this test.

Noise Output Winner-Husqvarna

Reduced noise pollution is often cited as one of the primary benefits of battery-powered OPE. Commercial users of backpack blowers also benefit from reduced engine noise while maintaining occupied residences or office buildings, and noise pollution-restricted areas. However, are commercial battery-powered options quiet enough?

We measured the decibel output of each battery-powered blower and our gas-powered sample. Measurements were taken at the ear of the operator and a 15′ offset. The two measurements show what the noise impact would be for both the operator and a possible pedestrian walking by. Readings were recorded at the highest captured decibel level according to our meter while the blowers were set for maximum output. We ranked the tools based on the at-ear decibel level due to the long-term potential impact on the operator.

Measured Decibel Output Results

Husqvarna is the quietest tool tested at 74.7 decibels. This is well below the OSHA threshold for required hearing protection. Furthermore, the Husqvarna has an impressive tone that is almost pleasant to the ear compared to a traditional backpack blower. In addition, Husqvarna is the quietest tool at our 15-foot offset distance.

Our top five finishers are under the OSHA 85-decibel threshold for hearing protection requirements. In contrast, the Greenworks Commercial blower was the only backpack blower over this 85-decibel threshold at the operator’s ear.

Weight Winner-Milwaukee

Weight is a big consideration for commercial users, who will likely be using the tool for eight hours or more daily. Battery-powered backpack blowers are faced with a tough compromise between a large enough battery for commercial use, while not weighing as much as a Volkswagen. We weighed all of our tool samples as a bare tool only and fully assembled with batteries inserted, however we ranked them by the assembled weight.

Our first-place finisher is Milwaukee with the lightest assembled weight of 32.08 pounds. This impressed the entire crew, especially considering that Milwaukee uses four large 12.0 Ah batteries.  A close second-place finish is Kress at 32.12 pounds. This is also impressive given the large suitcase-style CyberPack battery. Third place is Greenworks and Echo in Fourth. Husqvarna finishes in our fifth-place slot at 34.52 pounds and Stihl finishes the category in sixth-place at a hefty 36.16 pounds.

Measured Weight Results

Each of our tools increased by at least fifteen pounds when adding the weight of the necessary batteries. However, our bottom two finishers, Husqvarna and Stihl, saw weight increases of over twenty pounds after inserting batteries.  An interesting comparison to this is our gas-powered model. The gas-powered tool was the heaviest bare (empty fuel tank) tool tested but gained about two pounds when fully fueled. It is still almost six pounds lighter than our lightest battery-powered unit.

Features and Ergonomics Winner-Greenworks Commercial and Stihl

For this category, we focused on six major areas with our tools:

• Controls
• Grip Ergonomics
• Harness Comfort
• Ease of Battery Change
• Tube Adjustment and Storage
• Fit and Finish

Each tool was assigned a point value from 1 to 3 for each category, with 1 point being the most desired. The total score for all six categories was then calculated and the tools ranked based on the lowest total points to the highest.

Features and Ergonomics Results

In this category, Greenworks Commercial and Stihl tied for first place. Echo claimed our second-place slot, Kress in third, Milwaukee fourth, and Husqvarna in fifth.

Controls

Grip Ergonomics

Harness Comfort

Ease of Battery Change

Kress features the easiest battery change system of all of our tools. The large suitcase-style pack slides out easily with an easy-to-reach release button. Echo, Greenworks, and Milwaukee are all very comparable in terms of battery change. The individual packs are slid out or inserted in order to power the tools. Echo has a slight advantage over the other two, due to all the packs being vertically oriented and easy to access. Greenworks has a spring-loaded cover obstructing the batteries, while Milwaukee positions the batteries in different positions on the external frame.

Stihl and Husqvarna utilize more complicated battery change systems due to the size of the battery packs. Stihl features a rotating cam-lock to secure the battery pack once lined up. It is a little tricky to line everything up at first, but it secures the battery completely with no movement once engaged. Husqvarna requires two sliding plastic tabs to secure the battery from the side, which are difficult to align properly. A power cable must then be run from the battery to an adapter plug on the side of the tool housing. Additionally, the battery must be manually turned on before the tool can be turned on. Our entire crew agreed that this is annoying, especially when considering that it is impossible to reach this switch with the backpack on.

Tube Adjustment and Storage

Milwaukee and Stihl both utilize a telescoping tube design that collapses for storage. In addition, the control stick position is easy to adjust using a cam-pock system. This collapsing feature is ideal for shrinking the overall profile of the tool for storage.

All of our tools, except for the Echo, feature a clip or strap system to secure the tube to the tool body for storage. Milwaukee and Stihl feature heavy-duty metal hooks to secure the tube in a proper upright position.  Kress and Husqvarna both secure the tubes across the harness which causes the tube to hang off to the side and is awkward. The Kress hook also does not stay attached and comes off easily, which was frustrating for our crew. Greenworks secures the tube pointing upwards but uses a thin plastic molded clip that pops off easily and likely won’t hold up to long-term commercial use. Echo needs to include some form of attachment to secure the blower tube.

Fit and Finish

All of our tools tested are designed with commercial users in mind. Therefore we expected excellent fit and finish on all of the models that are still rugged enough to survive getting beat up on a job site or in a tool trailer. Overall we were impressed with the majority of the tools.

Echo, Greenworks, and Husqvarna all used heavy-duty fasteners and steel hose clamps in the construction of their tube designs. Milwaukee and Stihl utilized plastic connectors and clamps, however, they are thick and strong enough that they held up well during our testing without issue.

Kress uses a thinner grade of plastic on their tube and connectors than all of the tools we tested. This results in a lighter felt tube in the hand, but our crew expressed concern over this holding up over long-term, commercial use. During testing the plastic connecter that held the control stick in place repeatedly became loose and would not lock in place. We had to repeatedly tighten it with tools during testing to secure it.

Price Winner-Echo/GreenWorks Commercial/Milwaukee

In this category, we ranked all of our blowers based on the total kit price. Kit prices are most applicable as many professional users will be investing in a battery product for the first time. Due to the substitutions in battery packs used for testing, we built our kit pricing to mirror the setups listed above. We used the ACME Tools website to price as many of the tools as possible.

Price Data Results

We ranked our tools based on price and included this category in the overall rankings. Unlike other H2H tests, our entire test sample is made up of commercial-grade tools designed for demanding pro use. This levels the playing field.

First place in this category is a three-way tie between Echo, Greenworks, and Milwaukee. All three options are available as a kit for $1,500.00. However, Greenworks and Milwaukee both include dual port chargers in their kitted options while we priced the Echo out with a single rapid charger, as tested. The Echo is available as a kit with a dual port charger and two smaller battery packs currently. The price point of all three of these blowers is very reasonable when considering the power and performance of each as well as the additional tools available on the battery platform.

Second place goes to Husqvarna at $1,830.00. Stihl is in third at $2,410.00 and finally we have Kress in fourth at $2,680.00. Kress’ innovative battery and charger system comes with a hefty price tag. The Kress charger is almost $800.00 on its own. Husqvarna and Stihl are two of the most well-known brands in the OPE industry. While they represent a high cost of initial investment, they are both of extremely high quality with huge dealer support and other available tools and equipment.

Our pricing breakdown may come as a shock to some of you. Battery-powered options represent a significant price increase compared to traditional gas-powered options. For example, our pro-grade Echo PB-770T bower that was used as a comparison in some of our testing has an MSRP of $550.00. That’s roughly a third of the cost of our cheapest commercial battery-powered option. The initial investment of the Greenworks Commercial model ($1,500.00) would roughly cover the cost of two Echo PB-9010 gas-powered backpack blowers, the current world’s strongest backpack blower.

Best Commercial Battery Backpack Blower Winner-Greenworks Commercial

Greenworks Commercial emerged as the top performer in several key categories, including max airspeed and power output, making it a powerful choice for high-demand tasks. Stihl impressed with exceptional run-time, ideal for prolonged use, while Kress delivered outstanding air volume performance and record-setting recharge times, perfect for those prioritizing quick battery turnaround.

Milwaukee stood out for its lightweight design, striking a balance between portability and performance. Echo and Husqvarna also had strong showings, though they each faced challenges in categories like weight, ease of battery change, as well as some other comfort and ergonomic-related issues.

Overall Rankings Results

Best Value Winner-Greenworks Commercial

Ordinarily, our best value winner is a tool that offers outstanding performance compared to price. However, in this Head-to-Head our overall winner is also one of our most affordable tools! Greenworks tied for first place in our price category. When comparing the amount of performance the Greenworks is capable of, in addition to its features, our entire crew agreed that the Greenworks is the best all-around value of all of our tools tested.

Final Thoughts

Our comprehensive testing of battery-powered backpack blowers serves as a valuable buyer’s guide for professionals in search of the best tools for their needs.

As professionals evaluate their options, it’s essential to consider not just performance metrics but also the availability of local dealer support. Companies such as Echo, Husqvarna, and Stihl excel in this area thanks to well-established dealer networks and support services as well as box store options.

Choosing a brand with strong local representation can significantly enhance the ownership experience, providing easier access to service and replacement parts. Ultimately, the best choice will depend on specific needs—whether that’s raw power, battery life, or ergonomics.

Best Battery Backpack Blower | Video Review

Best Commercial Battery Backpack Blower Head-To-Head 2024 is a post from Tool Box Buzz

Hydraulic Impact Driver – Should You Have One In Your Kit?

When you hear the term “Hydraulic Impact Driver “you either know exactly what I’m talking about or you wonder if it’s some weird industrial tool hooked up to hydraulic hoses like a giant concrete saw. Well, I can assure you that if you do any work indoors, you should take a closer look at this tool.

What Is a Hydraulic Impact Driver?

So what is a hydraulic impact and how is it different from a regular impact? First off, a regular impact has three main parts a hammer, anvil, and a spring. As the hammer portion turns, if there’s resistance on the anvil, the spring loads up until it releases and the hammer strikes the anvil in the direction of rotation delivering that impact force into the fastener. The hammer and anvil mechanism is all metal so it is pretty loud when activated in quick succession. Check out this video excerpt from ToolStop where a Bosch employee demonstrates the impact mechanism.

A Hydraulic Impact is different in that it uses oil to build up pressure, when the pressure is high enough, pawls get pushed out on the anvil mechanism so that the hammer grabs them as it rotates. Then the pressure decreases, and the pawls retract until the pressure builds again. This results in a much quieter operation.

Benefits of a Hydraulic Impact over a regular

The first and biggest benefit is that they are half as loud as a regular impact. The new Dewalt boasts a 57% decrease in sound over their regular impact when driving 3″ screws into a pressure treated 4×4. That is a significant number. I can guarantee that all of us tradespeople will have some hearing loss over our careers, using a quieter tool when possible only makes sense.

The second benefit is the hydraulic mechanism due to the way it’s constructed, has more sustained torque. A regular impact is like hitting the end of a wrench with a hammer, a hydraulic impact is like putting a cheater pipe over the wrench and giving it a bunch of half-second tugs. Both will tighten the fastener, but one has torque on the fastener for a longer duration.

Killer Applications for Hydraulic Drivers

The obvious applications are anything indoors. MEP Rough-ins, steel stud framing, accessories (mirrors, grab bars, soap, paper towel dispensers, etc), device-ing out, and even doors and hardware. It isn’t just new construction either. Remodeling of existing occupied spaces can always benefit from decreased sound and vibration.

I do a ton of healthcare remodeling, hospitals, clinics, etc. Places that have to stay open even during construction. They always appreciate reduced noise and vibration, especially considering many places have normal sound levels rivaling the local library.

The last killer application is casework (cabinetry). Any time your head is close to the fastener being driven, the quieter the tool, the better it is for you in the long run.

Limitations of Hydraulic Drivers

There are some applications where hydraulic drivers are not the best choice. Longer and larger diameter fasteners like concrete screw anchors (TitanHD) and timber screws are hard for hydraulic impacts (and regular impacts) but in these cases, I usually switch to an impact wrench anyway.

The other area that hydraulics suffer from is extreme cold. I’ve had two Milwaukee Surge hydraulic drivers over the 8 years they’ve been out. The first one only lasted like 3-4 months because I left it on the job in the double digits below zero and I think the oil was too viscous and leaked out when I started using it for the day. I’ve never got an official confirmation from the brands that cold is detrimental for these types of drivers but I’ve read other reports online of similar scenarios.

Who makes Hydraulic Impact Drivers?

Up until a few months ago, Makita and Milwaukee were the only brands that made hydraulics. The drawback to this was that there has been no updates to these tools in the 8 years since they’ve been out. Now Dewalt just released theirs and it boasts quieter operation, less vibration, and more power than the Makita and Milwaukee. I don’t know if this new release from Dewalt will trigger updates to the Makita and Milwaukee.

What I do know is that if you’re on Milwaukee M18 or M12, Makita 18V LXT, or Dewalt 20V a hydraulic impact driver should have a spot in your tool kit.

First Impression

When we first got the new Milwaukee Circular Saw, we put it side by side with the earlier Gen 2 model. The first thing we noticed was that the new saw was much smaller and lighter. Once we made a cut with the saw, my first comment was, “WOW, this cuts smooth!” More on that later.

Accuracy

Not that a lot of people check their saws, but when we checked in the shop, our saw was a perfect 90 and 45 degrees.

Milwaukee M18 FUEL 7-1/4” Circular Saw 2834-20 Updates

Compact Size

Milwaukee tossed out the Gen 2 design and redid this new saw inside and out. They shaved weight and size off the gear case, shoe plate, and upper and lower guards to get a more compact, lighter saw.

Support Handle

The support handle has been moved down in front of the motor. This was done to separate the hands further and create a better opportunity for user control of the saw.

Actuation Safety Trigger

The previous circular saw model had an ambidextrous button that needed to be depressed to activate the trigger and power on the saw. This safety annoyed many users, me included.

Having to actuate this button sometimes made it difficult to use the saw in some positions, like overhead cutting or cutting rafter tails. Milwaukee removed the old button, eliminating the need for a thumb depress.

They changed it to a lock on/off button. Now, when the button is turned on, the saw can be operated from the tool’s trigger without any other safety functions or activations needed.

Finger Guard

You’ll notice a large finger guard surrounding the trigger. This was done to help prevent items from hitting or wedging against the trigger and causing an accidental power-on situation. We found this guard large enough to fit a winter-gloved hand inside.

Blade Adjustment Depth Detents

One nice feature added was the addition of depth detents at 1/2″, 3/4″, and 1-1/2”. This is a little feature that users will appreciate, and once it becomes second nature, they will just feel or listen for the detents and go!

Bevel Lever

The old plastic knob has been replaced with a robust “old-school style” metal lever. The issue we’ve noticed on the older knob was that it often would get loose, fall off, and you’d lose the nut to hold it on. The new lever is securely attached and requires a ¼ rotation to loosen and a simple push down to lock. The saw has two detents at 22.5 and 45 degrees.

Blade Guard Geometry

The new saw has a flared guard end that was designed to eliminate hang-up and improve compound bevel, miter cuts, and thin cuts. We made several test cuts trying to catch up with the guard, and while you can occasionally get it to catch, its design is way better than the Gen 2 model.

LED Light

Milwaukee moved the LED light, and it now points to the cut line and saw blade. We noted that this new LED location really improved the cut line lighting.

Dust Port

I don’t know any tradesmen who use circular saws with dust collection, but it sure is nice to have the option. Milwaukee changed the outer port to have a universal adaptor and eliminate an extra part that the Gen 2 had—one less thing to lose.

Dust Blower

The dust blower uses the motor fan to channel air to three slots in the front of the saw and direct the air to the blade. The slots can be seen near the new LED light location.

Blade Wrench

Milwaukee ditched the old Allen wrench and went back to an old-school-style wrench, placing it in a more secure location, into the saw body just under the battery location. This location seems more secure than the older location and is way less likely to back out.

The wrench itself is bigger and gives the user more to hold onto. You’ll notice a prying section at the wrench’s end, which is a carryover from the old diamond cutouts on blades—even though Milwaukee is eliminating them for a 5/8” round arbor on all their saws.

Guard Spring

While not necessarily new, if you turn the saw upside down, you’ll see the guard safety spring is more visible than the Gen 2. Milwaukee uses what’s called a “Double Bugle Spring,” compared to many competitors that use a J-Spring.

The “Bugle Spring” cones-open on both ends and makes it far less likely for it to come loose under stress and usage. Milwaukee is committed to making safe products. They use the double bugle spring because it’s very reliable option and they test it to the extreme. The goal is to have a guard that always opens and closes properly!

Increased Bevel

The new Milwaukee saw now has the capacity to bevel to 57 degrees versus the Gen 2, which beveled to 53 degrees. The cut capacity does lessen at this angle, but the ability to make that angle cut can be helpful to many carpenters.

New Motor

We like to describe this new motor as power-dense in a smaller size. Milwaukee didn’t shave weight off the motor, instead opting to increase the copper windings, making it 1/10 lb. heavier than the older motor.
Here’s an interesting explanation of motor power:

• Gen 2 Saw #2732: Motor produces approximately 2,000 watts of power with a 12 Ah High Output battery.
• Gen 3 Saw #2834: Motor produces 2500-2600 watts of power with a 12 Ah High Output battery.
• Gen 3 Saw #2834: Motor produces 3200 watts of power with a 12 Ah FORGE battery.

Vent Slots Under Saw

If you look under the saw, you’ll see some vent slots. Vent slots are not new to Milwaukee saws, but these vents pull in cool air to cool off the saw’s components and electronics.

Using this Saw – My Thoughts

Using this saw, I immediately noticed how smooth and effortless it was to make cuts. The bevel adjustment is a standout feature, and I truly appreciate the expanded 57-degree range, which offers more versatility for various cutting angles. The smaller, lighter design makes the saw more maneuverable, and the elimination of the thumb safety actuation switch is a welcome change, allowing for easier operation. The new LED location is another highlight, significantly improving the illumination of the cut line compared to the older Gen 2 model. Additionally, the dust blower does an excellent job of clearing the cut line, ensuring better visibility during use.

The Whole is Greater than the Sum of its Parts

The larger story here is that the new motor efficiency, updated electronics, and new batteries come together to give you a more powerful saw in a smaller footprint.

The following four core components all work together to enhance the Milwaukee M18 FUEL 7-1/4” Circular Saw 2834-20’s performance

1. M18 Forge Batteries

Milwaukee now has more powerful tab-less cell batteries and all-new battery pack construction that can charge faster. They come in the following sizes: XC6.0, XC 8.0, XC 12.0.

2. M18 SUPER Battery Chargers

Active cooling technology COOLCYCLE forces air through compatible battery packs. This airflow can cool overheated batteries within 90 seconds to begin charging.

3. Motor

This is the most power-dense motor Milwaukee has ever created. It has an increase of 36% more copper in the stator windings while reducing the overall size by 15%.

4. Electronics

More robust circuit boards and thicker wires are necessary to handle the increased current flowing between the new batteries and more powerful motors.

The new M18 REDLITHIUM FORGE batteries offer enhanced power in a smaller, lighter design, while the M18 Dual Bay SUPERCHARGER cuts charging time dramatically with innovative cooling technology. The POWERSTATE Brushless Motors have been refined for greater efficiency and power, and the upgraded REDLINK PLUS electronics ensure seamless communication between these advanced components. These enhancements culminate in the new 7-1/4″ Circular Saw, delivering more power, higher RPM, and improved ergonomics in a lighter package, setting a new standard for the M18 lineup.

Price and Availability

ACME Tools offers the Milwaukee M18 FUEL 7-1/4” Circular Saw in two configurations:

1. Bare Tool: $249
2. Kitted: $449, which includes a charger, bag, and a 12Ah FORGE battery. Model # 2834-21HD.

Overall Impression | Milwaukee M18 FUEL 7-1/4” Circular Saw 2834-20

We were blown away by the recent updates to this saw and immediately noticed the difference in power on the first cut. One of my crew described it as cutting “like a hot knife through butter.” Personally, I’d describe it differently. I’ve owned many pickup trucks, and I recently bought myself a used Audi Q5 as my personal car. This saw cuts with the power of my truck’s towing capacity but feels as smooth as cruising in my Audi.

Well done, Milwaukee.

New Milwaukee M18 Tool Improvements

Milwaukee Tools just held their annual PIPELINE media event where they unveiled the latest additions to their expansive product lineup.  The backbone of this years event was touted as THE NEXT BREAKTHROUGH in M18 FUEL ^TM. This next breakthrough is actually as series of iterative improvements across 4 key components that make up the M18 tool platform – batteries, chargers, motors, and electronics.

M18 REDLITHIUM^TM FORGE^TM BATTERIES

At last years PIPELINE event in 2023, Milwaukee announced their newest innovations to the M18 and MX batteries with the REDLITHIUM FORGE series. The M18 XC 6.0 FORGE battery was released taking advantage of a pouch style design that boasted similar performance to the M18 HD 12.0 battery in a package 30% smaller and 40% lighter.

This year the M18 REDLITHIUM FORGE XC 8.0 AND HD 12.0 batteries were announced. These batteries take advantage of a tabless cell structure currently found on the MX series FORGE batteries. This tabless cell structure benefits from a new laser welding process to connect the individual cells allowing for a more robust connection as well as unlocking a feature previously found only on the MX batteries that Milwaukee is calling COOL CYCLE. Open vents in the battery housing allow for active convection cooling when paired with the new SUPER CHARGER.

In addition to the faster charge times and increased power in a smaller package, Milwaukee claims these new batteries extend lifetime performance as well.

M18 Dual Bay Simultaneous SUPERCHARGER

With the release of the FORGE series batteries last year, Milwaukee introduced the new SUPERCHARGER series of batteries chargers. These chargers can recharge the FORGE batteries and previous generation REDLITHIUM batteries significantly faster, roughly 2X faster than the RAPIDCHARGER and 4-5X faster than the standard charger.

This year the SUPERCHARGER is incorporating the active cooling technology COOLCYCLE that forces air through compatible battery packs. This airflow can cool overheated batteries within 90 seconds to begin charging. Without COOLCYCLE ambient cooling could take as long as 20 minutes before charging can even begin. Additionally the airflow will keep the battery significantly cooler, aiding in the quick charge times and helping ease the strain on components over their lifetime.

As seen in the graphic above, the new 12.0 FORGE battery can charge cooled off a high demand discharge and charged in as skittle as 45 minutes with the SUPERCHARGER compared to 127 minutes for the previous gen 12.0 battery and RAPIDCHARGER.

POWERSTATE Brushless Motors

The POWERSTATE Brushless Motors also benefit from a next generation upgrade.  A new manufacturing process that Milwaukee is employing has allowed for an increase of 36% more copper in the stator windings while reducing the overall size by 15%.This is achieved by individual stator segments remain exposed exposed for high efficiency windings and then welded together to form the concentric ring.

REDLINK PLUS Electronics enhancements

To quarterback all these improved components, the electrical curcuits and wiring also recieved an upgrade.  The next generation REDLINK PLUS electronics are built around improved curcuit boards that are smaller yet more robust.  Additionally these boards can interface with much thicker wiring that is necessary to handle to increase current flowing between the new batteries and more powerful motors.

How do all these upgrades add up?

Most tool innovations these days are incremental and the margins by what makes a new version tool “better” can sometimes be hard to quantify or justify a sale.  Milwaukee has spent years making incremental improvements to 4 key backbone components with batteries, charges, motors and electronics.  In the past 12 months we have seen significant upgrades on all 4 of these components starting with the release of the FORGE batteries last year.  But what happens when all 4 get incorporated into a new tool designed from the ground up.

We were excited to see the first tool to incorporate all these upgrades are the new 7 1/4″ Circular Saws, both top handle/sidewinder and rear handle/wormdrive. The new 2834 model is set to replace the existing 2732 model in August 2024.  This newer has been redesigned from the ground up and features some new ergonomic improvements like a redesign of the sometimes cumbersome thumb activated trigger lock.

The new M18 FUEL  7 1/4″ Circular Saw has an increased cut capacity at 2 5/8″, a 1/8″ bump up from the previous generation saw.  The new POWERSTATE motors drive the blade at 6000 RPM, 200 RPM higher than before and produce a peak power output ~50% more.

Additionaly the newer saw is able to deliver all this new performance in a smaller lighter package.  The 2834 weighs in at 7.9 lbs, which is 10% lighter than the previous 2732 weighing in at 8.7 lbs.

While its easy to see how these new core components are delivering a significant bump in performance to the circular saw lineup, the potential to have similar performance gains in smaller packages across the M18 lineup is an exciting development.  While not all tools on the M18 lineup may see as large a performance gain as the saws we are eager to see how these new developments filter through the product lineup.

Best Rechargeable Flashlight Testing – Criteria

We performed three performance tests to evaluate these flashlights. Additional scoring categories included qualitative evaluations of ergonomics and features, size, and pricing. Lastly, we include a best-value category.

1. Submersion test.
2. Run-time test.
3. Peak Lumen test.
4. LUX Test.
5. Exterior housing temperatures – Some of these flashlights can get hot when on for periods of time.
6. Features | Ergonomics – Most of these flashlights are feature-rich. We identified, evaluated, and ranked 9 distinct categories for each flashlight.
7. Flashlight Beam Pattern – This is a subjective category where we share the characteristics of the flashlight’s beam. Because users prefer different beam patterns, we chose not to rank this.
8. Size and Weight – Size matters and weight can get cumbersome. We measured the dimensions and weight of each flashlight as tested (with Batteries).
9. Best Value – Oftentimes this category winner tends to resonate with most folks as it combines good performance and price.
10. Price – Price is always an important factor in determining which flashlight is best for you.

By following these comprehensive testing procedures, we can effectively compare and evaluate the performance, durability, and usability of each flashlight model, enabling informed decision-making for consumers and professionals alike.

Submersion Testing Procedure

Most flashlights are built to withstand heavy splashing and rain but should not be fully submerged. Waterproof flashlights, on the other hand, can resist water penetration completely for a certain period and depth.

When purchasing a rechargeable flashlight, pay attention to the IP or “Ingress Protection” rating. This rating is a two-digit code indicating the level of protection against solid objects (the first digit) and liquids (the second digit).

Solids are rated on a scale of 0 to 6, with 6 being the highest level of security, the first number corresponds to the size of particulate that is protected against. Liquids are rated on a scale of 0 to 8, with 8 being the highest. Products rated as impervious will have the highest number, but even these have limits. Manufacturers will list these limits so that consumers can make an informed decision.

We constructed a water submersion test rig consisting of a 10-foot 3-inch vertical PVC pipe that connects to a horizontal 2-1/2-inch clear PVC pipe. We placed the flashlights inside the clear pipe and slowly added water until the 10-foot pipe was full. The clear plexiglass allowed us to see the flashlight LED status. The valve on top of the clear plexiglass allows us to change out the test units without having to refill the tube.

All of the flashlights tested have some level of IP intrusion rating to prevent water and dust from harming the flashlight. The highest rating in the group was an IPX8 which certifies a 30 minute submersion at one meter (~3 feet). Our rig simulated a full ten feet of submersion which is significantly more pressure than the IPX8 level.

Water Test – WINNERS Tie: Braun, Olight and Streamlight

Among the 6 flashlights tested, Braun, Olight, and Streamlight emerged as the top performers, showing no signs of water intrusion after a rigorous 3-hour submersion test. These lights feature compressed o-rings that effectively protect their batteries and electronics.

Both the Olight and Streamlight lack external charging ports; Olight utilizes a magnetic charger, while accessing Streamlight’s battery charging port is located on the battery itself. Users are required to  unscrew the o-ring protected bezel and removing the battery. Braun’s design includes an o-ring sealed charging port accessible by partially unscrewing the bezel to expose the port.

In contrast, Fenix and Nitecore boast an IP68 rating but employ compressed o-rings and a rubber charging port cover, which likely led to water ingress. The Fenix failed after 32 minutes, and the Nitecore failed after 21 minutes in the submersion test.

Interestingly, all flashlights were inspected post-test, dried, and tested for functionality. The Fenix showed no signs of water damage and continued to operate flawlessly. However, the Nitecore exhibited water in all internal compartments and showed corrosion within a day.

The Milwaukee flashlight, with its IP66 rating and easily penetrated charging port, failed almost immediately in the submersion test. It senses when water gets into the port and shuts down. After a day or two, after drying out, it worked fine again.

Flashlight Run-time Output Procedure

A flashlight’s battery life indicates how long it can operate before requiring recharging. To assess this, we utilized the TKlamp TK2303 Light Meter to measure and document the runtime performance of each flashlight. While manufacturers provide run-time data, it’s often based on ideal conditions, which can create uncertainty about when a flashlight becomes impractical for use.

Our methodology involved not only measuring total run-time but also plotting the battery’s “ramp down” phase using the light meter. This approach allowed us to pinpoint the moment when each flashlight’s output dropped below 100 lumens, a threshold we deemed as signaling the need for recharging. During testing, all flashlights were operated at their highest continuous setting. We employed a time-lapse camera and digital clock to capture light meter readings every 10 minutes until the output dropped below 100 lumens.

The behavior of the flashlights varied during the run-time test.  Some flashlights throttled down significantly like the Milwaukee to just 136 Lumens within 10 minutes, while others remained at higher step down lumen levels.  To account for this disparity we calculated an approximate “area under the curve” or integral to find the Lumen-Hour  (lm-h) value output by the flashlight during the test.  You can think of this as an analogue to the amount of “Work” done by the flashlight.

Run-time Output Test Winner – Winner Olight

The Olight delivered a consistently strong performance, producing 3,326 lm-h maintaining over 450 lumens for 7 hours before dropping below 100 lumens. In second place, the Fenix with 2,827 lm-h maintained an average of 640 lumens for 4 hours. The Nitecore took third place with 2,537 lm-h and an average of 460 lumens over 5.5 hours.

Peak Lumen Testing – Winner Nitecore

Lumens is an SI-based measurement of luminous flux.  In simple terms its a measurement of of the total light output of the flashlight.  Specialized testing equipment is required to directly measure the lumens of a light source.

To test the lumens of the flashlights we used a TKlamp TK2303 Light meter.   This light meter has what is called an integrating sphere that works a light source diffuser to accurately measure the luminous flux regardless of differences in directional intensity.

Each flashlight was fully charged and placed into the aperture of the integrating sphere.  The lights were set to their highest output setting and the highest lumen reading after 1 second was recorded.  The results are in the table below.

LUX Procedure

What is a Lux?  A lux is a unit of measurement that measures the intensity of a light beam on a surface.  One lux is equivalent to one lumen per square meter.  In the previous tests, we directly measured the flashlight lumens with the integrating sphere in TKlamp light meter.

The lumens are the total amount of light that is being produced by the flashlight.  While Lux is the amount of light that is illuminating a surface a distance away from the light. Two flashlights with the same lumen rating may have vastly different Lux measurements depending on the focusing behavior of the lenses.  A broad diffuse beam will have a lower Lux reading than a narrow focused beam.

We used the candela sensor on our TKlamp TK2303 Light Meter to measure light intensity at a single point.   We can then use the candela reading across the beam-width and some math to determine the approximate Lux. When measuring the performance of a flashlight, it’s important to recognize that the light is not focused on a single 1-square-meter area, but is spread out.

Procedure

Record Maximum Foot-Candles:

1. Point the flashlight at the light meter and record the maximum reading in foot-candles (fc).
2. Rotate to Measure Beam Spread:
3. Rotate the Miter saw table until the sensor reads half of the maximum foot-candles (Max/2).
4. Record the angle at which this occurs (e.g., -10 degrees).
5. Continue rotating until the sensor again reads half of the maximum foot-candles on the opposite side and record the angle (e.g., +10 degrees)

Using these measurements, we calculated the beam width and the lumens. Knowing the beam width, we can calculate the area that the flashlight illuminates, to compare where the lens is spreading the lux.

LUX Test – Winner Nitecore

The winner of the Lux test was Nitecore with 1607.  This comes as no surprise given the very intense spotlight beam the Nitecore produces.  Second place went to the Fenix with 1066 and then the Streamlight with 754.

While its easy to generalize that more Lux is better, there is a nuance to the beam behavior that may be heavily influenced by user preference.  The bottom three performers in the Lux category all have very uniform beams with no intense center spotlight.  For users that prefer this kind of light [i.e. electricians, MRO and HVAC techs]  the Lux readings may have less of an impact.

Flashlight Temperature | Procedure

With the invention and ensuing widespread adoption of LED light bulbs, many homeowners have noticed the much cooler temperatures of equivalent lightbulbs.  LEDs are much more efficient at turning energy into light vs heat when compared to a traditional filament bulb.  However, this does not mean that LEDs are 100% efficient and when the power intensity is turned up enough, they can get extremely hot. We measured the external temperature of the flashlight on their highest setting and continually recorded their external housing temperatures using a Hilti thermal imager. The results are ranked with the coolest flashlights scoring top marks.

Temperature WINNER – Braun

A hot flashlight can be uncomfortable to use. The coolest-running flashlight tested was the Braun, reaching a peak temperature of 101.8 degrees Fahrenheit, followed by the Olight at 114.3°F. In third place was the Streamlight, with a temperature of 116.1 degrees Fahrenheit.
Most LEDs, components, and LED circuits are designed to withstand temperatures of 185°F (85°C) or higher without adversely affecting their lifespan or performance.

Features and Ergonomics – Winner Nitecore

Features are a critical factor in choosing a rechargeable flashlight, influencing its functionality, convenience, and versatility. Evaluating these attributes is pivotal in our assessments.

In our ranking, the Nitecore took the top spot with 13 points, closely followed by Fenix with 14 points, and Olight with 23 points. Nitecore impressed us with its intuitive design featuring a 2-button operation, 7 light modes, battery and brightness LED indicators, USB-C charging port, and tactical blip [on/off] switch. It stood out as the most feature-rich and user-friendly flashlight in our tests.

Fenix offered similar features with additional brightness levels but fell short due to the absence of battery and brightness LED indicators, which affected it’s score. Olight excelled with excellent brightness levels, a robust pocket clip, and rich feature set. However, its single-button operation and proprietary charging cord resulted in a lower ranking.

Milwaukee M18 15mm Random Orbital Polisher Kit Review (Model# 2684-22HD)

Milwaukee M18 Random Orbital Polisher

4/5

Manufacturer: Milwaukee
Model number: 2684-22HD
Price: 529.00
Power source: M18 Battery
Motor size: Brushless
Weight: 5.16

This kit comes complete with a carrying case, two Milwaukee M18 6.0AH batteries, and a rapid charger.  Our initial thoughts were that the Milwaukee Random Orbital Polisher was very comfortable to hold, and also very strong in the power department. In this review, we will cover the features of this polisher, report back on the battery life, and test the Milwaukee Random Orbital Polisher in many different applications by myself and in the hands of a professional detailer.

Milwaukee Random Orbital Polisher Specifications

• Battery Platform: M18 FUEL
• Motor Type: Brushless Motor
• Length: 17.26″
• Weight: 5.16 Lbs
• Warranty: 3 Year
• Head Size: 5″
• Speed Settings: 8
• RPM Range: 2,650 to 5,100

Carrying case

Like most Milwaukee products, the Milwaukee M18 15mm Random Orbital Polisher Kit includes a carrying case. I find the carrying cases that Milwaukee includes handy for tool organization and shelf storage. I keep most of my polishing pads and chemicals in this carrying case when not in use.

Rubber Grips

The Milwaukee M18 15mm Random Orbital Polisher is extremely comfortable to hold. The front and rear handles are molded with a soft and durable rubber grip. The rubber grips have a molded diamond shape pattern to improve hand grip. I used this tool to polish two cars, a boat, car headlights, and plastic Jeep windows. One of the best features of this tool was how comfortable it was to hold.

Weight/Length

With the M18 6.0 Ah battery attached, the Milwaukee Random Orbital Polisher weighs in at 7.13 pounds and 19.5″ in length. I found the weight and length of this polisher to be on par with most other battery-powered polishers. Naturally, a battery-powered polisher will be a little heavier and a little longer than a corded tool due to the added battery. A battery-powered polisher is a high-demand tool. Therefore, the included 6.0 Ah battery hits the sweet spot between not making the tool too heavy and having enough battery to last a reasonable amount of time while polishing.

Battery Life

Battery life is one of the most common questions regarding almost any cordless power tool. While polishing I often take small breaks, adding more product, taking a sip of water, or wiping my work area. With these small breaks in polishing, I found that one battery lasted me a little over 50 minutes. Additionally, I also tested the polisher and NEVER let the tool shut off. The trigger lock was engaged and I ran the polisher at 3700 RPM until the 6.0-ah battery died. In this setting, The Milwaukee M18 Polisher lasted exactly 44 minutes and 36 seconds. I think that is a pretty good amount of continuous time from one 6.0-ah battery.

I typically do most of my polishing in my garage or driveway. Having two fully charged batteries will get me through most jobs. If additional batteries are needed the rapid charger will charge the batteries fairly quickly. I also tested a completely drained battery and the rapid charger charged the 6.0-ah battery in exactly 56 minutes. It should be noted that while using the tool at a higher speed, the Milwaukee Polisher performed at 100 percent power right until the battery was getting close to depletion. It then had a slight loss of power. This loss of power was beneficial to me because it gave me a heads-up that the battery was getting low but still allowed me to finish the area I was working in. However, when I tested at mid-speed (3700 RPM), the Polisher shut off when the battery died.

Milwaukee Random Orbital Polisher Power

The Milwaukee M18 Random Orbital Polisher is no slouch in the power department. As I previously mentioned, this polisher provided corded-level power the entire time it was used until battery depletion. The strong Milwaukee polisher has 8 speeds to choose from, ranging from 2,650 to 5,100 RPM, which can be selected by the easy-to-read dial on the top of the tool. The placement of the speed selector is in a good location on the top of the tool and it was not in the way while using this polisher. The trigger lock is also placed comfortably and can easily pushed in to keep the polisher on without having to hold the trigger.

The Milwaukee Polisher did not stall during normal use. I had to apply heavy pressure to get the polisher to stop spinning, but it was still not completely stalled out. The amount of pressure that I used is not needed for normal polishing. This confirmed how powerful the Milwaukee Polisher is.

Milwaukee Random Orbital Polisher – Professional Use

Although I am pretty skilled when it comes to keeping my toys polished, I also put this tool into the hands of a true professional polisher. I loaned the Milwaukee M18 Random Orbital Polisher to Matt at MaxSport Auto Detailing here in CT. Matt is a professional detailer who offers expert detailing services, and I must say that he does an excellent job. In addition, he was already familiar with this Milwaukee polisher as he had already owned it.

Matt told me that the Milwaukee Polisher is not his first choice as he typically uses a corded high-end professional polisher. However, Matt did provide feedback from a pro perspective. Matt was quick to say that although this may not be a high-end polisher, it is a very solid polisher at a reasonable price point (much less than his professional polisher). Matt explained that he often uses the Milwaukee Polisher when he is in a situation where he needs to be cordless. Although Matt already owned this polisher, he still tested it out for the day to refresh his memory.

Professional Opinion

While Matt tested the Milwaukee Random Orbital Polisher he had plenty of “pro” opinions to offer. First Matt commented that the Milwaukee Polisher was a little heavy. When polishing all day long every ounce counts and can certainly take its toll on the body. Matt also felt that the length of the Milwaukee Polisher was a little long. He believes that a shorter polisher would allow him more maneuverability when polishing vehicles like a Lexus that has a lot of angles.  However, he noted that weight and length are user preferences. Although these were some key points, it’s important to remember that when using a battery-powered polisher, naturally there will be a little extra length and weight due to the added battery.

Professional Insight

Matt also liked that soft grip of the Milwaukee Polisher more than his professional polisher, and he commented that the polisher had really good power with 2-5 lbs of pressure applied. The biggest thing that was brought to my attention was that the motor of the Milwaukee Polisher polisher was slightly unstable or unbalanced on startup. This meant that each time the polisher was started, it wobbled slightly on the vehicle surface until it reached polishing speed. The professional polisher that was also on site had no wobble on startup.  I was able to take the 5″ backing plate off to check the motor and bearing system. Everything was tight, and there were no adjustments that could be made. I didn’t notice this wobble until Matt pointed it out, but this may be something on the radar of a pro.

Matt concluded by saying that he prefers his corded professional polisher. However, there are certain jobs in which he has to break out the cordless Milwaukee Polisher. Although the Milwaukee Polisher may not meet the expert level, Matt said that if it was all he had to use he would have no problem making a living using the Milwaukee Polisher. Matt’s opinions are that the Milwaukee Polisher is great for homeowners up to professional car detailers who are just starting. We also agreed that it would appeal to people already on the Milwaukee M18 battery system.

Final Thoughts on the Milwaukee Random Orbital Polisher

The Milwaukee M18 Random Orbital Polisher is a dual-action polisher. Dual-action polishers are safer to use than standard rotary polishers. It is comfortable to hold and has strong power like a corded polisher. Each M18 6.0 AH battery will last about 45 minutes. If you purchase the kit you will have a second battery to keep on the charger ready to go.  After testing the Milwaukee polisher on several different applications and putting it in the hands of a professional detailer, we agreed that this is a solid polisher for many different levels of use.

Buy it now

The Milwaukee M18 15mm Random Orbital Polisher Kit can be purchased as a kit and comes complete with a carrying case, Two Milwaukee M18 6.0AH batteries, and a rapid charger for $529. The Milwaukee polisher is priced similarly to other competitors on the same level. It should be noted that the Milwaukee Random Orbital Polisher is also offered as a tool only for $299.00. Buying as a tool-only can make the Milwauke polisher very affordable if you already have the M18 batteries. Additionally, the Milwaukee Polisher is also available in a 21mm version with a 6″ backing plate for $329.00. It should be noted that the 5″ & 6″backing plates are universal and can be switched between polishers. Backed by Milwaikees’ 3-year warranty, there isn’t much to worry about as far as longevity.

Head-To-Head Testing Criteria

Our team meticulously evaluated these cordless SDS-Plus rotary hammers, across five categories and ranked them.

1. Performance Test – Speed at drilling various size holes in concrete.
2. Efficiency Test – Run-time test of recommended battery normalized for Watt-Hour capacity.
3. Size and Weight – Size matters and weight can get cumbersome. We measured the dimensions and weight of each concrete drill as tested with batteries. [not factored in overall ranking]
4. On-Board Dust Collection – we tested and ranked features.
5. User Experience- Combination of features, ergonomics and subjective user evaluations.
   Additionally we included price, and best value charts for your consideration.

Silica Dust

The Tool Box Buzz Team recognizes the significant dangers that exposure to silica dust can pose to workers. While we always strive to use any and all personal protective equipment, there are times when we may omit certain PPE during testing. We want to remind anyone that uses concrete cutting and drilling tools to use proper protective equipment to prevent silica dust exposure.

Performance Evaluation | Drilling Test

This test evaluated the speed in which the tools could drill 3-inch deep holes into concrete with 4 different bit sizes. The drilling substrate used was 3,500 psi concrete blocks, 12” x 24” x 4.5″ deep. These concrete blocks had cured for 6-months.

Performance Test Procedure

Drill Sizes Evaluated: ¼”, ⅜”, ½”, and 1″ SDS-Plus rotary drill bits.

1. Five holes drilled to a depth of 3” using a depth rod and blue tape for accuracy.
2. Each hole was timed, and an average recorded.
3. All drills equipped with new Milwaukee SDS-Plus rotary drill bits.
4. Operators instructed to maintain consistent pressure and let the drill do the work.
5. Dust extractors were not utilized.
6. Technique emphasized to ensure fair comparison.

Performance Test Winner – Milwaukee

Milwaukee dominated three out of the four speed tests, earning an impressive overall score of 5. DEWALT’S 60V FlexVolt secured second place with an overall score of 15, excelling particularly with the 1-inch bit test. Hilti and Ridgid claimed third place with an overall score of 18. Metabo followed with a score of 21. The Metabo was not a remarkable tool, but was a consistent “power-house performer.”

Individual Test Results | Top 3

¼” Rotary Bit Results

• Milwaukee: 4.19 seconds
• DEWALT 60V: 4.63 seconds
• Hilti: 5.49 seconds

⅜” Rotary Bit Results

• Milwaukee: 4.93 seconds
• Ridgid: 5.24 seconds
• DEWALT 20: 5.88 seconds

½” Rotary Bit Results

• Milwaukee: 4.36 seconds
• Ridgid: 5.43 seconds
• Hilti: 5.57 seconds

1” Rotary Bit Results

• DEWALT 60V: 14.52 seconds
• Milwaukee: 21.63 seconds
• Metabo: 24.04 seconds

Note on DEWALT FlexVolt 60V Rotary Hammer

The DEWALT Flexvolt was an extremely powerful and heavy tool allowing it to shine in the 1-inch drill bit test and subsequent chipping evaluation.

Efficiency Evaluation | Normalized Run-time

Although run-time becomes less critical with sufficient battery capacity, we acknowledge it’s importance in specific scenarios such as with commercial users, installing numerous drop anchors in a day. With so many tools, battery voltages and sizes, we normalized run-time and investigated the efficiency of the tools energy available. Obviously some battery packs contain much more potential energy so it’s important to try and compare them based on the “size of the fuel tank”.

Efficiency Testing Procedure

1. Vacuums removed for this test.
2. All tools equipped with fresh batteries.
3. 1/2″ Milwaukee drill bits drilled to 3″ depth.
4. Operators instructed to maintain consistent pressure and let the drill do the work.
5. The total number of drilled holes were counted and scored.

Holes Drilled Per Watt-Hour – Winner Makita 18V

The Makita 18V drill claimed the top spot, surprising us all with it’s performance. This drill managed to complete 66.5 holes with a single 4 Ah battery with a 0.92 holes drilled per watt-hour.

Interestingly, the Makita 36-volt model, despite having twice the available watt-hours, only completed 82 holes, representing just a 23% increase in hole count which equated to only drilling 0.57 holes per watt-hour. This unique comparison between the two Makita drills highlights a design prioritization of efficiency vs power.

The Metabo 18 volt came in second place with 0.85 holes per watt-hour. Third place went to the DEWALT 20 volt with 0.82 holes per watt-hour.

Size and Weight – Not Used In Final Rankings

In the realm of SDS-Plus rotary hammers, size matters to some users. We measured the dimensions and weight of each drill, as tested (with Batteries / handle), and ranked them accordingly.

We felt the two most important factors for these drills were the weight and head length. Having a lightweight tool coupled with a compact size can be an important factor for some users. While we didn’t include this ranking in the final scoring we did account for the size and weight in our user experience rankings below. It’s interesting to see that most of the smaller / lighter tools didn’t perform as well as the heavier tools in the speed testing. Likely this is due to the size of the gear boxes, motors and housings.

In this category, the Kobalt drill boasted the shortest and lightest stature among all drills tested, clinching the top spot. Following closely in second place was the DEWALT 20V, which also showcased a compact form factor and lightweight design. The Ryobi drill secured third place in this ranking.

On-Board Dust Extractor Evaluation

On-board dust extractors are designed to be used as a system. Eight of these tools were sent with compatible on-board dust extractors to evaluate.

Dust Extractor Procedure

We tested the on-board dust extractors, ranking eight criteria:

1. Capacity – We drilled ½” x 3” holes until we saw dust “ant-hills” form around the hole. At that point we consider the capacity of the dust extractor full.
2. Visual inspection of capacity.
3. Filter cleaning – Self cleaning or manual function
4. Filter replacement – ease of removal.
5. Depth of hole with attachment.
6. Depth guide – ease of adjustment.
7. Replaceable head.
8. Weight.

On-Board Dust Extractor – Winner Hilti

The Hilti came in first place in the on-board dust extractor category. It was feature rich with its replaceable head, depth guide, and filter cleaning options. Despite clinching the top position, the team collectively noted that the dust canister could be improved by being translucent for better visibility, and the filter could be easier to detach from the canister.

In terms of “capacity” performance, the Hilti canister maintained dust extraction efficiency for 14 holes. Milwaukee drilled 10.5 holes, and Makita 40V managed 15 holes.  Surprisingly, the Metabo HPT drilled 21.5 holes, and the DEWALT 20V drilled 22 holes, but didn’t excel  in other feature comparisons.

User Experience – [Tie] Winner Hilti and Makita 40V

User experience (UX) encompasses the overall satisfaction and ease of use that a tool provides to its users. In this category, our team of Pro users provided subjective rankings for the user experience while handling these rotary hammers. This ranking was based on various factors experienced, including grip, balance, vibration, line of sight, ease of use, fatigue factor, and overall comfort.

The team identified four drills as top performers during testing. The Hilti and Makita were tied for first place, closely followed by a tie between the DEWALT 20V and Milwaukee 18V. All four of these tools exhibited commendable performance in our testing and were noted for their user experience.

Rotational Force | Bind Test – Not Ranked

When a drill binds, it has the potential to violently spin the tool around potentially injuring the user.
To assess the performance in binding situations, we conducted a subjective test by drilling a 1-inch diameter, 8-inch, deep hole in concrete and side load force.

3 Types of Safety Shut-Offs in Rotary Hammers

1. Accelerometer – An electronic component integrated into the tool that detects sudden rotation and initiates an automatic shutdown.
2. Mechanical – Utilizes a straightforward mechanical clutch mechanism whereby the tool continues to run, but the bit stops spinning when the clutch is engaged.
3. Electronic Overload – An electronic overload function is activated either before the mechanical clutch or during specific binding scenarios. This electronic overload serves to safeguard the electronics, motor, and battery, while also acting as a safety feature in certain situations.

Rotational Force Findings

During our testing, all of these tools effectively shut off when the tool was bound up and the user had a firm grip on both the tool and the auxiliary handle.

Standout tools featured all three safety mechanisms, predominantly found in higher-end models such as those from Bosch, Hilti, Makita (40-volt) and Milwaukee. These tools successfully incorporated all three mechanisms that we were able to activate during field testing.

Chipping Test – Winner DEWALT 60V

Our chipping testing methodology was primarily subjective in nature. We employed our drill testing blocks to conduct the chipping tests.

TBB Crew users utilized the rotary hammers to break up the test blocks, after which they provided feedback via a form detailing their chipping experience.

The consensus from our testing suggests that there’s a “secret sauce” combination of impact energy and beats per minute (BPM) that yields optimal chipping power. This mix of factors seems to be instrumental in achieving productive chipping results.

The DEWALT 60V was the largest and heaviest tool in the group and with 4.5 FT-LBS of energy, it’s no surprise that it excelled at chipping, taking first place

The DEWALT Flexvolt was a “jack hammer disguised as a drill  ~ TBB Crew Wes Bartosik

The Makita 40V came in second. It has tons of power and minimal vibrations felt, due to its well throughout decoupling. The Milwaukee 18V came in third place. It delivers an incredible amount of energy on impact and was very controllable while cutting scribe lines.

SDS-Plus Rotary Hammer | Price – Not Included In Final Scoring

Most manufacturers offer these rotary hammers in kit form, bundling the tool with a battery optimized for performance while maintaining a manageable weight. Achieving the best user experience hinges on finding the right balance between weight, balance, and power to accomplish tasks efficiently.

For your reference, we have listed bare tool pricing below, although this wasn’t factored into our final scoring. As an illustration of the cost range, the Kobalt is available as a bare tool for $99.00, while the Makita 40-volt model is priced at $589.00. Please refer to the attached chart for further details.

Best Cordless 1-Inch SDS-Plus Rotary Hammer – Winner Milwaukee 18V

While impact energy undoubtedly influences a tool’s performance, it’s crucial to recognize that it’s not the sole determinant of effectiveness. Other factors, such as RPM and BPM, also play significant roles in achieving the desired outcome for the user. Harmonizing impact energy, RPM, and BPM is essential to optimize the tool’s overall efficiency and effectiveness.

Decisions should be based on considerations related to ergonomics, safety, and mechanical performance. Balancing these aspects ensures that the tool not only performs well but also prioritizes the safety and user experience of the user.

It’s noteworthy that when ranking our categories, we assigned double weight to performance scores, considering it the most valuable category.

Milwaukee claimed the top spot in performance, secured second place in dust extraction, and ranked third in both user experience (UX) and chipping. Its overall performance stood out as the clear winner.

Second Place honors go to the Makita 40V.  This Makita excelled in UX, chipping and dust extraction. The Makita 40V was a favorite among the crew, tying with Hilti for the top spot in UX.

Hilti rounded out the podium in 3rd place.  The Hili was also heavily sought after by the crew and ranking first in the UX category, boasting the best dust extraction, and coming in eighth in performance testing and fourth in chipping.

Tied for fourth place was Metabo and DEWALT 60V. Metabo stood out with it’s second place in efficiency and scored well in both user experience and chipping. The DEWALT 60V was impressive in the chipping tests and performance.

Best Value 1″  SDS-Plus Rotary Hammer – Winner Ridgid

This category winner often strikes a chord with users as it showcases an SDS-Plus drill that performs admirably while being more budget-friendly. In many respects, it’s a category of significant importance, sometimes overshadowing the top-ranked contender, crowned king of our 1″ SDS-Plus Rotary Hammer Head-to-Head Test.

The Ridgid 18V, priced at $269 as a bare tool, claimed victory in this category. Despite landing in seventh place overall, it delivered commendable performance, securing a solid fifth place rank in our performance testing. We often refer to Ridgid as the “hidden gem” of the tool industry.

Best 1″ SDS-Plus Rotary Hammer | Closing Comments

1″ SDS-Plus rotary hammers are essential tools for contractors seeking efficient, versatile, and reliable solutions for drilling and hammering tasks in concrete and masonry materials.

We often receive inquiries about our final rankings and understand that there are numerous ways to compare tools.

Our primary goal during testing is to attain repeatable and consistent results. We make sure to share all the data from our tests so that users can re-rank the tools according to their preferences. If there’s a specific aspect you don’t find relevant, feel free to remove it from the matrix above and re-evaluate the rankings accordingly.

Diablo Amped Rebar Demon Masonry Drill Bit

A few years ago, Diablo introduced the Rebar Demon masonry drill bit solution for SDS Plus and SDS Max with a full carbide cutting head. The Rebar Demon combined Diablo’s great concrete drilling solution with the ability to cut through rebar. While those bits were definitely a game changer, they didn’t address the need for a better dust control solution. Dust control is an extremely important issue when it comes to worker health, jobsite cleanliness, and proper hole preparation for adhesive fasteners.

The Diablo Amped Rebar Demon addresses the dust control features that were missing in the original Rebar Demon. The Amped Rebar Demon has a new design that includes an exceptionally high-quality full carbide head and a stainless-steel sleeve for dust control. The innovative shaft design allows for the seamless suction of dust through a hose adaptor, resulting in a clean and efficient operation.

Milwaukee New M18 FUEL Tools 2024 Released at World of Concrete

The ToolBoxBuzz Crew has been given early access to the new releases from Milwaukee for the World of Concrete 2024 expo. This article will feature the new Milwaukee M18 FUEL tools debuting this week in Las Vegas. Milwaukee continues to expand the M18 FUEL line with four new tools that cater to professional contractors and skilled tradesmen.

M18 FUEL Duplex Nailer and Nails

The new M18 FUEL Duplex Nailer is tailor-made for demanding professional users in the concrete trades. The M18 Duplex Nailer is as much as seven times more efficient than a traditional hammer and nails. More importantly, it reduces the potential for fatigue or injury to the user. The Duplex Nailer will drive up to four nails per second. Additionally, it has a tool-free jam clearance mechanism and depth adjustment.

The M18 FUEL Duplex Nailer is supported by Milwaukee’s new line of duplex nails. These nails are available in two sizes; 8D, 2 1/4″ driveable length, and 16D, 3″ driveable length. The individual nail strips feature increased spacing between nail heads for easier prying. Both of these products will be available in Q3 2024.

M18 FUEL 6 1/2″ Circular Saw

Milwaukee has updated its circular saw lineup with the new M18 FUEL 6 1/2″ model. The newest version of this saw features a “new to world” depth detent system and positive bevel detents. These two upgrades are a great improvement over the previous generation of the saw which was featured in our Best Cordless 6-1/2″ Circular Saw Head-to-Head.

Additionally, the new saw features 20% more power and 40% faster cut speeds, thanks to Milwaukee’s POWERSTATE brushless motor. When paired with a M18 High Output 6.0 Ah battery the saw is capable of up to 300 cuts per charge. An electric brake, LED work light, rafter hook, belt hook, and magnesium shoe plate are all standard features. The new 6 1/2″ circular saw will be available Q2 of 2024.

M18 FUEL Overhead Rotary Hammer With Integrated Dust Extraction

This tool is the first of its kind and provides enhanced ergonomics and dust collection for overhead drilling applications. Overhead work is often extremely fatiguing and difficult to do. Milwaukee’s new rotary hammer simplifies this task with new features and trusted technologies. A side handle provides better control and posture while working. By integrating the dust collection, Milwaukee reduced the overall weight of the tool and eliminated the need for additional accessories. The AUTOSTOP technology has been proven across the full line of Milwaukee drills. The Overhead Rotary Hammer also utilizes this technology to prevent bind-up and over-rotation. This new hammer is a purpose-built solution for small ceiling anchors and holes up to 5/8″ in diameter. Available May 2024.

M18 FUEL PACKOUT 9 Gallon Dual Battery Dust Extractor

Our final addition to the M18 line for World of Concrete combines some of the best technologies Milwaukee offers. A handy cordless, rolling, dust extractor that uses two M18 FUEL batteries and is PACKOUT compatible? Sign me up. The new 9-gallon extractor is compatible with the Milwaukee VACLINK for remote activation of the vacuum when paired with a compatible tool. Furthermore, the vacuum features a low airflow alarm system to alert the user when the vacuum is no longer achieving effective dust extraction. The described features and technology, combined with a mobile 9-gallon vacuum will provide an excellent solution for contractors on the move who don’t want to be attached to a traditional cord. Available Q4 2024.
