Buy some solid carbide drills. They work just fine red hot.
Drill small holes and then work up - easier to work it that way.

ok, I'm having trouble drilling it. ?I used a cobalt drill and a carbide

Even after I took the end I need to drill up to a dull red heat.

Any suggestions?

Are they dulling quickly or just not penetrating the metal? I've had
decent results with a HiRoc drill.

Just not penetrating. However, I realized after I posted this that even
though the metal gets softer when you heat it up, it doesn't revert to
its pre-hard state until you get it past the critical temperature. I can
drill them now, but it still kind of rough.

I'll check out the HiRoc drills. Thanks!
