I want to make a round hole in some aluminum stock. The diameter woiuld be about 1 1/2 inches. The siz is not critical it will just allow for the pasasge of the feed lines for a faucet. The aluminum will be 1/8 in thick. I have a table top drill press. Will a standard hardware level hole saw be appropriate? I think with that size circle the slowest speed would be right. What about lubrication? Dry, water, oil or what?
I am trying to avoid a starting hole and saber saw or some other such way.
