Use a small gas welder with a small tip, 0 or 00, set the gas for a neutral flame, put on safety glasses, face shield and leather welding cape.
Put the flame on the broken bolt, as the bolt heats up and starts to turn cherry red, keep the flame on the bolt, just as the bolt turns molten it will explode out of the hole.
The hole will be quiet clean with small amounts of slag. After cooling run a drill bit down the hole, then clean the treads with the correct size tap.
I have used the above method to remove broken manifold bolts from an engine on two occasions.

Yup. Never heard of that..... and I'll be 60 this year. I have heard of a metal
disintegrator and that's the only magic tool I've ever seen used that makes
broken stuff come out of tapped holes.
