I have used the same Milwaukee RA for over 20 years. This is the "D" handle one that has the RA adaptor on it. Only time I had a problem was a couple of years ago when I used it with a 6-1/2" abrasive hole saw to cut holes in a plaster ceiling. The hole saw grabbed (mainly because it is not variable speed) and knocked a tooth off a gear. No big deal to fix and it was time to repack the gearcase with new grease anyway. Looking forward to another 20 years with it.
A buddy of mine once told me of the problems he was having with Hole Hogs. Seemed he bought one from the place with the orange roof, used it a few times and had problems with a gear chipping. Wasn't using anything big, normal 3/4 and 1" augers. He exchanged it and soon after had the same problem with the new drill. Now he gets his money back and buys a third Hole Hog from one of those internet tool places. Hasn't had a problem since.
What does that tell you about Home Depot?
