Jim:
 I have been saved by my left hand drill bits a number of times! They are so
good I broke down and purchased a whole set! It was hard to find a set but
they were not too expensive. I have broken so many EZ-outs and bolt
extractors. The problem with that kind of removal is that you are fighting
the whole system and just making it tighter and that's why the thing broke
in the first place.
 Go with some heat and try a backwards drill bit. I paid $20 for my set.
