Alistair, I've a dumor 'speeder' or at least that's what i've always called it - is that what you mean? it spins at something like 20k with the smallest jacobs chuck. basically a high speed balanced motor with a chuck on the end. its used in the drill press chuck, simply as a way to hold it, the drill press is never turned on. actually I turn the breaker off because by rote i'd hit the green button, don't ask how i discovered that little personal weakness.

sensitivity is increased if you make one of these, plans irrc in one of our sponsor's books.

for very find work, its a sensitive drill press table, counterbalanced the table raises up into the drill. I've done #85 holes with this, it works.

This is a Dumore sensitive drill press I have on eBay now. It is 0-5/32" capacity, 17,000RPM. They list new around $800.00.

Nice!

I have had a high speed, precision drill press for a long time. It is called a Unimat. Selection of speeds up to 10K RPM and with a fan speed control, I have continously variable speeds.
