Maybe a better way is going to a good hardware store and buying a LEFT
HANDED drill bit smaller than the major diameter of the threads. Then
carefully drill your pilot hole with a smaller RIGHT Hand drill. Then
use the LH drill, in most cases the grab of the LH drill will back
out the broken bolt. If not your ready for the Easy Out. Just make
sure you turn your drill in reverse before drilling L Handed.
Major diameter of threads not bolt.
