Harder steel is more brittle, in general.  Best to get something VERY
hard and drill the center out of whatever is stuck in the hole.  Start
small and build up to the minor diameter of the thread pitch of the
original hole.  If you stay centered you will eventually see evidence
of threads.  When you do, stop drilling and try prying what's left out
with a small pick.

If you bugger the threads up you can always use a Heli Coil insert to
make it good.
