those masonary bits your talking about are the same thing as the links I put above the ones that I said will work in a pinch, ordering is better but I tried those masonary carbide tiped bits when I didn't have any others and I can get them at home depot so again the work in a pinch ray is right the hole isn't precise but for handle pins it works also to prevent wandering just hit the spot with a punch to get them to stick
