Personally, I set the RPM to suit the diameter of the drill and the material being drilled.

I agree, just took the 350 as a base line or reference. The speed charts, after looking them over have a too fast feel about them.

Drilling is like any other machining process in my mind. If in doubt start at the recommend base line and adjust accordingly.
