The drill could not drill a 3/8 hole that was already tapped. Luckily I already had a quality nozzle that did the job. When I tried to cut the faucet into the drill hole, the faucet got so stuck I was afraid it would break. I had to look locally for a good faucet. In my opinion, it's not worth using. Do yourself a favor and buy the best quality made in the good old USA.
