Payback time!!!!

What are you using the drill for?
For occasional access in tight spots, my cordless 14v DeWalt has worked well- but only has a 3/8 chuck.

When the time came for running lots of MC in wood studs, and I would need a nail-eater bit, I gor a sorded drill...the Milwaukee 1/2" "close quarter drill, to be exact. It broke on the fourth 5/8" hole.
After repair under warranty..three weeks...it worked fine for hundreds of holes, untill I again hit a nail, and SNAP....that drill spent almost three monthes "in repair," until the vendor replaced it. The Milwaukee rep- a fine gent who once told me I wasn't enough of a "pro" for a "real" drill, and should stick to less powerful homeowner makes- asserted that I was abusing the tool, and should get a different tool.
Please note that Milwaukee's literature is devoid of any suggestion that there are ANY limits on their tools.

Both times, I was saved by my Harbor Freight, made in China, clone of the "hole hawg." $300 vs. $75...the choice was easy!

Now Milwaukee does make a heftier drill, one that is not nearly as cumbersome as the "Hole Hawg." After my expereinces with Milwaukee, I agree with the rep that I need a different drill.....I just haven't decided if it will be yellow or blue!
