I probably have to drill 4 holes, 5/8" diameter, through the steel base of an engine hoist. (Harborfreight - mis-matched holes).
I have the drill press but not the bit or the experience. What kind of drill bit do I need? I assume I need to use drilling oil. It is better if I can find something at a Home Depot or Toolmart rather than waiting for an online order to come.
Thank you
