fired this volley in
:

doing the drilling. The spade drill I use has high pressure coolant
through. If someone turns off the coolant for some reason and presses
the start button the spade drill and part are destroyed. I know this
because an employee twice forgot to turn the coolant back on after
turning it off for some reason. GRRR.

Ayup, and yes.

And a twist drill can do that all day long, too, so long as the spindle
is rigid and the coolant is keep on.
