Can it be used to put screws in wood, concrete or metal without drilling a hole?
If we need to drill a pilot hole anyway, why don't we just use drills to put the screws in?

I like driving a few screws by hand once in a while because it's an incredible forearm workout (in case you're seeking more purpose in your exercise regime). At least with wood; I've never tried concrete.
