I bought a new Milwaukee 36 volt hand drill 3 years ago and with one of the fat batteries it will drill all day long.Here in WNY our ice is usually anywheres from 5-12 inches and I used to carry an extra battery but don't anymore.I usually run and gun and drilling 15-30 holes doesn't even slow this drill down. Just have to be careful as its one powerful drill so hang on tight.I always use the handle and brace it against my leg and have had no problems with it.I carry 2 Strikemaster auger bits for it, a 5 inch and my 8 inch.
