Can you point to a good source for this information? I'd like to do
better than my normal "hmm, this drill is about so big, guess I'll run
in second notch this time".

I've got it on one of my sites... All very conservative numbers with
coolant factored in.

Stainless really should never be drilled without coolant.... Unless you can
spin at 2 RPM.
