I want to make about a 1.25" hole in the base of a few food cans.
What's the best option?

A flat wood bit will **** through thin metal like this.

It will make a hole that is shaped like a cows ****.

I haven't tried this with steel, but I converted a flat aluminium bowl
into a lamp shade. I cut the hole for the bulb holder with a flat wood
bit. It turned out nice and neat, actually. The aluminium is a bit
thicker than a tin can, which might make it easier I suppose.
