Re: Re: tiny rivet heads

Some years ago I built a microscopic mill for a production plant and I think it might work for you also.

I bought a dental air turbine. It runs at about 400 to 500 thousand RPM (no, I did not get one zero too many). It was not
expensive either if I remember correctly. Do not buy the whole handle or they will charge an arm and a leg, just buy the
replacement turbine and then make a little housing for it so you can mount it in the regular CNC spindle.

Remember to add a drop of oil now and then or an oil mister to the air supply. The plant machined millions of small parts with
the one I built without wearing it out.

Check with dental supply houses. There was a company in the "Home Shop Machinist" that used to sell a turbine mounted in a
little handle that they made but I do not remember their name.

There are all kinds of dental burrs, both carbide and diamond.

Good Luck
