Got a good center punch??? Strike it in the middle (center) so the drill bit doesn't walk on you.
Stat small and work your way up to but not bigger than the threaded part if the bolt.
If you can get some left hand drill bits for the last couple sizes it may just come out. If not you get close enough and there is enough relief on what is left you can get it out with an easy out.
If all else fails get close enough to use a chisel at the outer edge or just re- tap the threads.
Patience which I have little is the word.
