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
