Spehro mentioned step drills - that is the way to go.

I have a tool box full of Greenlee Chassis punches. 3/4" means not much
for the bolt.

Step drills are low cost - made for sheet metal. I have a set of them
and pick one of three to be in the range I need.

I need to put a 3/4" diameter hole in the front of my kitchen range hood.
Never mind why -- that's kind of involved. It's stainless steel, about 20ga,
and it would be a real PITA to dismount it and take it anywhere. I really need
to make the hole with the unit in place.

What's the best tool to use for that job?
