I am a bingo-card junkie, and I just got my reply from NSK America for their
air- and electronic quill-motors (even dental hand-pieces). They make
air-motors with collets in "installable quill form" up to 200,000 RPM, as I recall,
having glanced through it all only once. They also have some High Freq.
electronic quill-motors that run on up there in the tens of thousands of RPM.
The site is <A HREF="www.nskamericacorp.com">www.nskamericacorp.com</A>. I am sure you must bring money, probably
in a sturdy wheelbarrow!
