This didn't happen to me, it happened to a friend of mine today. It reminded me of the kind of stuff that used to happen to me when I worked on cars a lot many years ago. Anyway, he is trying to fix a big exhaust leak in a Chevy 2.8l V6, and he discovered that one of the exhaust manifold bolts was broken off. He tried to drill it to get an EZ out in, but the 1/8" drill bit broke off, about 1/4" of it. Now he's really feeling depressed. Is there any solution short of EDM? He doesn't want to pull the engine if he can get around it. He needs to sell this car.
