Just my luck. Tonight I was match drilling #30 the forward fuselage skins to the lower longeron and had a brand new cobalt drill bit break off while drilling one of the holes common to the gear tower weldment on my RV-8. I have attached a snippet of the plans with the area I'm talking about highlighted. The bit broke inside the hole, so I can't grab it with vise grips. There is a hole where the bit would have exited the inboard side of the gear tower weldment, but the bit isn't sticking out yet to grab onto, and I can't use a punch to push it out because the weldment has a steel bar running forward to aft that blocks access to the hole.
Does anyone have advice on how to get this bit out? This hole is going to be enlarged to #19 for a screw, so I can get away with enlarging this hole a bit while removing the bit. Is there such thing as a bit extractor?
