what's an edm machine? that's a new one for me.
I'd suggest something like what mike does, if I understand him. I once
broke off a hardened e-z out in a bolt on a jet-ski pump. I ended up
using ~10 tiny ti drill bits (they broke a lot) to drill the bolt around
the e-z out away enough that I could remove the e-z out, and still not
damage the threads. then, of course I had to get the remaining bit of the
bolt out, but that's another story.
