Not unless it was reasonably loose. Usually when faced with this, I drill into the bolt with a very hard drill bit a tiny bit thinner than the bolt - ie if it's a 3/8 bolt, I drill in first with a 1/8 drill to create a guide hole, then after with a 5/16 drill to cut right through, yet not harm the threads. You have to be very careful to stick to an exactly straight course. After the hole is cleared, I pull the threads left from the bolt out as far as I can, then use a 'clearance' tap of bolt size to re-tap the hole.
Depends how far down you drill doesn't it.
try to drill strate trough it than you should be able to turn it but dont drill to far
