Rated 4.3 out of 5 by 23 reviewers.
Rated 5.0 out of 5.0 by tool works great The grinder works as expected. The battery life exceeded my expectations. March 12, 2015
Rated 5.0 out of 5.0 by Excellent Product Line Excellent quality and good battery life. As a pro, I understand why this is the preferred line of tools. Can expect 15-20 years of battery support. Many others discontinue after 2 or 3 years. January 13, 2015
Rated 4.0 out of 5.0 by Great For The Right Application I added this to my M18 set a year or so ago, and have been pretty happy with it; but it has it's limitations. The build quality is top notch, but it will NOT replace a corded grinder for heavy duty work, or use with large surface area disks (like paint removal pads) in any but the smallest applications. And (along with Milwaukee's great little vac) is the biggest battery eater in the tool line. What it WILL do is save you a lot of set up time in places that don't have great access to power or the need for a lot of pressure. I do property maintenance on a lot of old cabins, and this thing is GREAT for "planing" stuck doors and windows, prepping small repaired areas for paint or stain, etc, without having to run 300' of extension cord for a 10 minute job. If I could have only one grinder, this wouldn't be it; but as a compliment to my corded tool, it's is well worth the price. November 29, 2011
Rated 5.0 out of 5.0 by Very handy grinder This is a nice battery powered grinder. It does use the batteries up but it works as well as my plug in grinder. Also it's really nice when you get locked in a job site for cutting the chain off at the gate. (Last Friday night) August 26, 2014
Rated 1.0 out of 5.0 by bad investment Purchased this grinder for work and truly disappointed with how it works.... Lacks power that it should have and it kills batteries to fast... Had to grind 4 TACK welds that with a normal grinder would be fast but this tool took for ever... Killed a fresh xc battery and barely cut them same thing happens when cutting off bolts it has this weird shaking stop thing it does when too much force is applied and stops the motor.... As far as cordless grinders go I think I'm going to dewalt they atleast do the job they are intended star only because it makes u have one otherwise it's a neg5 July 30, 2014
Rated 4.0 out of 5.0 by Better than expected! I bought this on sale with a single purpose in mind, to use a cutoff disc for a project. I have been pleasantly surprised with the number of times i used the tool; ive used it for grinding, for trimming and cutoff of tubing and angle iron. It has enough power to finish a small job like trimming and finishing. I like the milwaukee tool line and this has been a nice addition to the ones i have. August 6, 2014
Rated 4.0 out of 5.0 by This is a great grinder. I already had a drill with two baterries so i got this next and I absolutely love it. This is a great grinder. I already had a drill with two baterries so i got this next and I absolutely love it. August 5, 2014
Rated 5.0 out of 5.0 by Very Handy tool I was skeptical when I bought this not believing that a battery powered grinder could really be very handy. I was proven wrong this is now my go to tool for all kinds of jobs. It will not replace a corded grinder for heavy work but is great for doing quick jobs. The XC batteries are a must as this will chew up a standard battery pretty quick. September 26, 2012
