Features

  • Brushless motor of the angle grinder requires no brush changes.
  • DEWALT grinder's brake stops wheel in 2 seconds or less on average

  • Great tool with no cord!
I've used corded angle grinders for many years and I never expected a cordless angle grinder to be worthwhile. I was pleasantly surprised that this angle grinder works amazingly well. With steady use, the battery will discharge after several minutes, so it's helpful to have a second battery on standby. However, for most standard applications it's worth not dealing with a cord getting in the way. This has plenty of power to work as expected. ... show more

  • Great tool. Terrible Battery Life!
I love DeWalt tools. I really do. I think almost every tool I own is a DeWalt. And this is a really good grinder. I wasn't even that irritated that it didn't come with a battery or any blades, because the 20v batteries are so interchangeable. The only issue I have is the extremely short battery life! And I do mean SHORT. A fully charged short pack gives you about 5 minutes of use on this thing. Switched it to the thick pack that I use on my chainsaw and that bumped it up to about 15 minutes or use. If you are a contractor or something other than a home improvement DIY'er, this thing would be a serious disappointment! Everything else about it, I love. The grip, the weight... But man, it sucks the life out of a battery! ... show more
