Awesome grinder. I have the original m18 grinder and this one is just a whole new level. I really like the variable speed and grip profile.

Milwaukee tools are by far the best! Love the lock on power switch. Saves on fatigue from holding the trigger down while working. It easily shuts off with the touch of your finger.

Nice tool, good quality. Works well as expected with good safety features. I only have the 5.0 battery and it works well with it.

Milwaukee is quality period . I own 3 Milwaukee tools and love each one, I plan on buying more in the future. I could have bought dewalt cheaper as a package but knew the quality of Milwaukee was much better. I do more than just around the house stuff but less than a every day professional.
I have not used my grinder yet. I got it for Christmas and I do not have grinding wheels, cut off wheels, and buffing wheels for it. I like it and I always want it a grinder for Christmas. I do no want to borrow my dad’s grinder, I just want it my own grinder from you guys so I got one for Christmas.
I just simply bought this for cleaning up and refinishing vehicle frames. It’s really nice not dragging a cord or a hose around. Has plenty of power and battery life to do what I need.
Everything works as advertised or better. Very thankful for the available slide switch, brake and adjustable speed (rpm)
This battery-powered Grinder serves up great power and convenience. Quick & easy metal cut-off as well as a smoking carving tool with the Kutzall shaping disks. Can't be happier.
this tool is the best of its kind. The power and durability is amazing. very high quality performance. very comfortable. I advise to buy. I only use Milweukee.
Variable speed is a nice feature. Haven't used it enough to test its durability. Being Milwaukee I'm sure it will work well!
