Rated 4.6 out of 5 by 16 reviewers.
Rated 5.0 out of 5.0 by No Cord = Awesome I love this tool. I use it with to wire wheel welding slag and stuff like that. No cord is the best thing ever. I have a corded grinder with a stone wheel for heavy use and needed a second one equipped with a wire wheel. Two grinders with cords would be mess. The bad: Grinders take a lot of power. This thing goes through batteries like candy. It's not the tool's fault, just physics. If i am constantly using this i can get like 15 minutes out of a 1.5AH pack. But the occasional use in welding and it lasts a while. I need to get a 3 amp hour battery pack. It has plenty of power, they did not dumb it down to get more battery life. It is heavier than plug in grinders, even before you plug in the battery pack. Buy it, but don't expect to get a long run time under heavy use. If you need to do heavy long grinds you should have a plug in unit or multiple 3ah packs. August 13, 2013
Rated 5.0 out of 5.0 by Powerfull tool ! Very strong running grinder, guard is big and in the way a lot, but the tool does a great job. October 7, 2014
Rated 5.0 out of 5.0 by Quick Change Wheel Release? The Quick Change Wheel Release is widely featured, but never detailed, explained, or demonstrated. The User Manual never mentions it. My new DCG412 has "Quick-Change" on the hub, but you need the tool to get wheels on and off. Try to find useful information buried in all the safety and legal goop. December 17, 2012
Rated 5.0 out of 5.0 by great tool finally a tool that is needed for almost everyday fab guy that has no cord. August 19, 2014
Rated 4.0 out of 5.0 by Great for some uses Grinder was light and super easy to use, worked awesome for quick cut off jobs of small bits of grinding and stripping paint. Only problem is the battery life, but thats somewhat expected with a cordless tool! Overall great for small uses and super portable, but if you plan on doing larger projects a corded item would be recommended March 22, 2014
