I didn't expect high quality for a low price but I expected more than I got. Any time the drill bends in half without breaking, something is wrong. I bought these for my cordless drill, primarily for wood, which is what they are good for. They are so soft I can't imagine using them on anything harder than a tin can. I actually had a few flatten the top on 1/16 inch sheet metal, press harder and they doubled. No, I will not buy again.
