Thanks for posts. Just starting out . Have some manuals but none with
this information. What would be the gold standard of reference manuals
for this information. Had wanted to buy a drill for mostly #30 and 40
drill bits but was at a loss with all the rpm ranges. Sounds like for
aluminum I should be looking at a higher rpm range than I originally
thought.
I had thought this group was amoung other things to use members as a
resource. I suppose I shouldn't be suprised that someone should
criticize me for asking what to some might be obvious, but I don't
think this is a community that eats its young. I might need some more
help in the future. KM

A brief Google search came up with the following info related to drill
speeds:

http://www.micoks.net/~dbennett/dpsc.html
A Palm application

http://www.collinsclubs.com/woodwork...speedchart.pdf
A PDF chart, not totally useful since it only goes as high as 3000 rpm (
meant for drill presses)

http://www.auto-ware.com/techref/drillspeed.htm
A simple chart which only has fractional sizes by sixteenths.

Scroll down to the bottom for information which will allow you to
calculate RPM and feed rates for amy material and any bit size.
