I've had better luck with Milwaukee tools. Only Dewalt I ever had a problem with, not sure if it could really be called a problem. Before I found a guy that could laser cut my steel out for targets, I use to cut them out with a torch, and grind the edge's smooth. Used a DeWalt 4 1/2 angle grinder, that spun at 10,000 rpm. Wore out after 8-9 years, figured out the brush's were shot, so bought a Milwaukee, still runs good. But only used it for a couple years and went with the laser cut.
