[Boatanchors] CCW drill bits

[Al Parker]

Hi John,
    I've bought small left hand drills (1/16" I think) at a good hardware 
store.  Set screws are hardened steel and very hard to drill thru, but a LH 
bit might grab enuf to turn it.  The problem with screw extractors "Easy 
Outs", is that they need to operate inside a hole in the item to be removed, 
and I've never seen one small enuf to do what you need, plus you've got the 
same problem of drilling thru the set screw.  (and small ones snap easily.)
    The epoxy dab on allen wrench might work, I've heard of success that 
way.
good luck, 73,
