Review on Speed-Titanium Impact Driver for Enhanced Compatibility in Any Project by Isaac Maze

That came out before it put a hole in your fist! I'm an electrician and have been using "step bits" or whatever they're called for about 5 years. I figured a cheap kit for my exposure would be fine for what I do, but I was wrong. This set is a waste of money. Apparently not for hitting because it burned out before a 1/2 inch hole was made in the steal. I guess I have to stay with an expensive client.
