They make tap extractors. Otherwise, you're gonna have to get a punch and try and break it apart inside the hole. Done that before, it's not a fun job.

You can find them at a Grainger or Fastenal store, or a local machine tooling supplier. If ya know anyone that is a machinist, they could loan ya one. In alot of instances you will have to break it into small pieces. Always use lubricant when tapping. Dry tapping will get you in trouble most of te time. USE SAFETY GLASSES!!!!

Also when tapping go slow. Turn your tap in 1/2 turn then turn it back out 1/2 turn. Then turn in until it grabs again and go 1/2 turn in and then back out 1/2 turn. Do that till it bottoms out. Then remove the tap and spray the whole down with brake kleen or something to clean it out. Always use oil or a thread cutting lube with tapping.
