I drill many a broken bolt out where I work. I seldom (never) use easy out's and
EDM is not an option on an entire jet engine. We usually drill it out to size or
nearly size, pick out remnants and re-tap. This way I avoid breaking easy-outs.
I
have however broken more taps than I care to admit and have drilled them out
with
carbide drills in a hand held drill, often in ridiculous positions. You just
have
to be careful. I have tried the break apart method and it resulted in a lot of
damage to the threads.
