Dewalt Grinder is Good
This grinder is good to go thus far. I don't use it under heavy or commercial applications, but it's working fine for moderate use. Product as described. Vendor good and shipped fast. Be sure to order grinding and/or cut wheels if ya don't already have them.

Probably the best cordless grinder out there
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

Works well, happy with it, wish guard was easily adjustable
This works fine. I got it to work on motorcycle gas tanks. I wish the guard was adjustable. Also, I already has the 20v max batteries but only the batteries for the drills. With the drills, the small 20v max batteries I have work forever but for this thing, I only have 2 minutes or so until they run out so I'd recommend getting the larger battery if you don't already have one.

Great grinder. I have used it a lot, No problems, If your grinding heavy material, Battery life does shorten, but that is to be expected. I would buy it again

Es potente considerando el tamaño que tiene. Lo utilicé para cortes en concreto y funcionó muy bien. Si consideran su compra sería ideal que lo hagan con una batería Flex Volt por lo menos de 9 amperes, pues su consumo es alto para mantener su potencia. Espero continúe así la potencia del equipo.
