    • Probably the best cordless grinder out there
Color: Multi
The kick back protection works amazing for when it bites and shuts the grinder off. The button lock placement isn’t the best but the lock on is nice. It’s got a lot of torque and is hard to bog down. It’s probably about the same torque as a corded one. I like the brake feature and it works well. But it does chew down the battery’s really quick, even the 5ah power stacks. I would highly recommend it to any mechanics who need a good grinder ... show more

    • great little grinder, light and portable for quick cut or grinding jobs
Color: Multi
I've been wanting one of these for a while - I have several Harbor Freight corded grinders and it's a pain to run cords for just a quick cut or to grind a small task. This is light, powerful and fast with my 4 inch diamond wheel. It is a little rough on batteries though. If you have a lot of work, get a lot of batteries or stretch out the cords ... show more

    • Really comfortable grinder with slide switch.
Color: Multi
I got this to add to my suite of 20v tools. My kit came with the more typical trigger switch but I don't like that feature, especially for longer sessions of grinding (just my preference). This grinder is powerful, lightweight and the ergonomics are great. The motor is powerful and efficient, and did a relatively long grinding session, cutting rebar, grinding welding beads flat (so people don't see what a crappy welder I am!). And it has a nice brake, that came in handy when one of the rebars pinched the wheel, and it basically "slipped" as the brake should, preventing an unpleasant kickback, since this is a powerful tool. Also like the slide switch design, eliminating the need for a separate lock-out switch you have to deal with. It has a shaft lock button on top of the grinder, allowing easy on/off installation of the wheels, and not sure if they made it this way but I don't need tools to remove/install wheels. Overall great 20V Mas XR grinder, and love the Dewalt 20v system, overall. ... show more

    • Trigger is excellent, ergonomic tool.

Dewalt is the best for the money and power you can’t beat a classic Dewalt tool. My predecessors used Dewalt, now I do. Great tool to have as a craftsman to cut many things. Always wear PPE and avoid having loose clothing. I’ve had these things suck up my old shits every now and then lol.
