Wow. I'm glad I just started reading this group. What a helpful bunch here!
I'll the the original poster would never have thought about looking it up.

Not everything that you and I might take for granted is common knowledge among
some of the new builders - or even somewhat experienced ones. And sometimes
those of us that have been doing "it" for a score+ years forget that not
everybody knows the basics.

To answer the original post - the smaller the drill bit the faster you
can/should turn it.

In my experience:

for sheet metal work (drilling #30 holes) the fastest air drill you can buy is
none too fast.

A sharp split point bit and an accurate center-punch help too.

our experiences differ.
my experience is that most drills spin too fast, particualrly for
aluminium.
the speed of your average cordless battery drill is about right and
allows far better control for freehand drilling.

I agree with the other guy, the faster the better. I don't see how
using a heavy electric drill with a heavy attached battery makes it
easier to control. My Sioux with a lightweight air hose is much easier
to work with than any cordless I have tried, for rivet hole sizes,
anyway. If I'm going to be using my unibit or a larger twist drill I
agree that an electric might be easier to work with.
