I just bought this drill and tap from Chicago Latrobe. This set is very convenient for the store. It includes a correct size drill with the required hand tap. Just drill a hole and screw in the faucet. You should also have a T-handle, but a crescent-shaped wrench will do, but you can't start tapping right away. I didn't think I would need such a complete set until I bought it. These taps are also good for retapping or cleaning old threads. I also use the following: Reduced Shank Bit Set, Listing #190F, 8pc.
