Thanks Mac for the tip. I will remember that one. I showed one of the guys
at work how a left hand twist drill works(ground left hand rotation) for
removing a broken bolt. He says don't you still need the easy
out.........nope, about that time it broke loose and spun the broken bolt
out. There is nothing like them for a broken bolt. They reduce the pressure
on the middle of the bolt and unlike an easy out they don't expand the bolt
and make it tighter. There's another one you may or may not know. :-)
