How to remove a stuck flexible installer bit?
Congratulations on using a very good tool for that project, but condolences on getting it stuck! Definitely too expensive to abandon. The only way I know to recover a stuck bit like that is to back it off. You may need to borrow a stronger drill such as a Milwaukee hole hog or some other gear driven heavy duty drill. In the future, always try to use a very strong drill as a flex bit tends to bind easily as it worms it way through thick stacks of framing. Also try clearing the debris from the bit trail by backing off the bit a little when engaging a thick bore and letting debris clear before pushing forward. This will help minimize binding.
