scary_jeff Posted July 1, 2009 Report Share Posted July 1, 2009 If the bolt is really tight, the flat screwdriver might just mangle the slot you create. Then you have to drill a 1 or 2 mm hole through the bolt; when you rewind the drill, the bolt might come out. If not, go 0.5mm bigger bit and try again. Ideally you would use a reverse drill bit, as this is much more likely to work first time as you drill into the bolt (in reverse)... but it's unlikely you will have one.The other approach I've seen work is to drill a hole in the bolt, then use a 'weld' adhesive to fix a small allen key into the hole, and finally undo the bolt with the welded in allen key. This is a bit of a last resort if you have reached the max drill bit size that won't damage the hole that the bolt is going in to, and the bolt still hasn't come out.
