Hi all,
I have used this trick when drilling out bolts with buggered up heads.In
my machine shop business,I keep several common size LeftHand turn drill bits
around;just for drilling out damaged bolts and screws. After I center punch
the damaged head, I use the Left Hand Turning drill bit to go through the
center of the screw.Most of the time, the bolt comes right out on the drill
bit before I finish the drilling procedure.
Yours, H4(Howard)
