Re: Oh boy...



UGH. Mercury is the coolant - a metal liquid. Likely very active.

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?
