really have to keep the cutoff tool close to the chuck.
Where did you get it from? What sort of stuff are you making?

It has been recommended as the best seal material for Stirling engines,
which I've been wanting to do some work on, so I've been keeping my eye
open for info on the stuff.

I have machined a fair bit of plain Teflon, however.

Small Parts, Inc., where it costs $$ (but this is a small part of a
commercial machine, so it's OK).

We're using it for a sliding bearing.
