          • If that option isn't available, do your best to grind end flush
          • Take super-extra-care and use the center punch to get a punch in the exact center (or as close as you can)
          • Drill a tiny pilot hole all of the way through - taking care not to break off this pilot drill bit.
          • Step up through different drill sizes until you come to the one you use for the broken bolt extractor you are using.

          • Grab the torch and heat the holy hell out of it and then try to remove it.
          • Most of the time, the heat will help guarantee success. 



Most of the time, the heat will help guarantee success. However, when that doesn't work then you need to press ahead an install a TimeSert. How To - Thread Repair
