    broken tap

    I hope I can describe this so it can be understood but here goes. The tap has threads for cutting and valleys for clearing away the cuttings so those "valleys" should provide a means for getting some grip. I once had success by heating a small hex key and bending it into a U shape that fit nicely into the "valley" gaps and then used an adjustable wrench to wiggle it back and forth til it worked free. Good luck.

    Good post! blowing a sharp blast of air also helps remove any chips. Once it starts to move keep turning it back and fourth. Work it this way until it's out.

    a good screw extractor set should be able to get it out for you too . I have a pro set, and i also was bought a set of those "grabit's" the pro set you have to drill the hole first through the center of the bolt then twist your extractor bit into the hole. let it grab and then back it out slowly. The grabit works about half of the time as long as the screw isn't too small.

    The problem is you cannot drill a hole in a hardened tap. :grrrrrr:
