I have a 60 gallon upright air compressor and it seems to run the air
drill fine. I've never seen an electric drill that turned RPMs in the
thousands. My Makita cordless at work might do a few HUNDRED RPM. When
I bought my Sioux, it was the highest speed air drill I found at an
aviation tool supply. Oh well, that's life...

I have an ancient direct-drive air drill I found at a Princess
Auto here in Canada. No gears in it, and it turns at some insane speed
like an air die-grinder, maybe 15 or 20,000 RPM. It sure does a nice
job on small holes in aluminum, very little tendency to skid.
I wonder if it might be worthwhile to make a threaded adapter for a
1/4" chuck and clamp it into the collet of a 90-degree die grinder? Or
are there any pistol-grip die grinders?
