We'll grab the Milwaukee 3/4" for busting lugs off truck rims. Only because the Engineer let us test the 1" for a month before he moved it to another shop. It was the first thing that went on the tool request list. They do make the 1" in a pistol grip. That 3/4" gets them every time, though!

I just literally set the Milwaukee 4" grinder on fire. Nice blue and yellow flames. Long story. I'm seriously thinking of replacing it with the cordless version.
