- Use a Dremel tool with a cut-off wheel to cut a slot in the top and then use an impact wrench (not an air wrench, this is the kind you hammer on) with a straight bit in it to loosen it. Centerpunchin

- If you have to drill it out, try renting a magnetic drill press (mag drill) McMaster-Carr has some thread inserts better than Helicoils if you just happen to mess up the threads. If you drill the bol

- There are no tricks. There are some techniques. I've written about them at length in http://triumph.cs.utah.edu/sol/tech/BrokenBolt.html - the most important technique is patience. It *can* be done.

- I have had success removing broken studs by welding a nut to the end and using a wrench to back it out. You can get a much better grip on it with a wrench than with vice grips. I always apply a LOT o

- As Bob mentioned above, that is a trick: I have a small BALL END dremel bit. Only a 1/8" diameter, but with a steady hand seem to be able to get a "dimple" into the offending bolt. Once dimpled, my
