Good excuse to throw a 2.3 in there.
It works good if the bolt is softer or equal in hardness to the surrounding material. You have just the opposite going on. The key is to drill out the center of the bolt and take enough material so you can get a tap that's the correct size for the bolt to start cutting the damaged bolt. The hole you need to drill in the damaged bolt really needs to be the diameter of the bolt minus the treads. Maybe a little smaller but you see where the problem is. The bit you are using is damn near the same size as the bolt hole. Anything off center starts to cut into the treads in the head. It may be a last resort effort but it sounds and looks like that’s where you’re at.ZX2_racer wrote:This drill and tap idea. How much of a problem will it be?
