I want to drill a 1.25" hole in a sheet of (probably) 12ga stainless
steel. I'm not sure of the grade but it's the type commonly used for
commercial (restaurant) range hoods and tables.

How do I go about this? Hole saw? Carbide tipped? 3/8 electric drill?
Do I need to use a drill press? Slow speed? High speed? Water cooled?
Oil?

TIA


Use a hydraulic punch.
