Those extractors that are just drill bits with a biting tip always break. I don't think they ever work except when the broken bolt offers zero resistance. Make sure you use PB Blaster on it...
Can you get some vice grips on the other end of the broken bolt?
Edit: The extractors that work are the ones where you carefully drill a hole in the center of the busted bolt and then hammer a splined rod in there that you can then use a special tool on to spin the entire bolt. I like Scotts idea. I'd even try a dremmel instead of the chissel but again, be careful not to hit the threads of the hole.
