Now I know why I do so much better than my competitors sometimes... Just
got a call from a potential customer who wants to drill .250" holes in
radiation hardened 316l stainless while spraying the unit with mercury...
1" thick stainless with no coolant.

Sounds like a prank call at first, but turns out to be a nuke application.
All my competitors turned him away. Wonder why.

If the drill "bit" breaks, they close the door, destroy the whole container
and start over with a new unit from me.

I'm guessing that I need to run at 50 RPM or less. Any thoughts?

Possible thoughts:-

avoid cobalt\ radiation issues
avoid copper/

avoid nonferrous metals mercury issues

Other than that. High cobalt bits run slow :-)
