While attempting to add an Ethernet run to a exterior wall (no crawlspace access beneath the wall - oops) I have managed to get my flexible installer bit (example in link) completely stuck. I have a 6A corded drill and it can't budge it; I've also tried vice grips and yanking on it as hard as I can.
I'd really rather not just cut the rod off the bit - it was pretty expensive. Does anyone know of any tricks on how to remove a bit that has become stuck?
