We have a job to drill a bunch of headed aluminum rivets, about
20,000 pcs. They range from 11/4" to 1 1/2" long, 1/4" shank with a .110 hole all the way through. Normally we drill them on the CNC lathe, but with this quanity it will take a long long time. What I want to do is double or triple the drill RPM, the machine will be running at
4000rpm and the speeder I want to run at 4000 or more rpm. I did some searching on google but all I could find is this, looks perfect but for $3400 it pretty steep.
