Milwaukee is a good name, but these driver bits are
terrible. They cam out and tear up the heads of just about anything I use them on. I've tried them with drywall screws, deck screws, general purpose screws, - forget about brass screws.
They are clearly marked #2 Phillips, so it's not because they are JIS or something weird. I don't know if there is something about being extra hard and extra strong that makes them suck so bad. They claim to have a custom machined tip, whatever that means. Whatever it is, they work equally poorly with a straight drill or an impact.
I don't recommend that you buy them if you ever come across them.
