Just happen to have both of my Milwaukee 1/2" drills in the same place, don't happen often.

Both drills easliy over 10 years old and the big one has honed many engines with a real sunnen hone which takes some big azz arms and a strong back.

Then the drill get's so hot you can't can't hold it no more with heavy leather gloves on, many times and it still works like new.
