I wuz gonna ask that too.

But, I imagine you can grind the cutting edges so they'll work, but the
flutes sure won't wanna move the chips up out of the hole, will they?

I suppose to remove a bolt you don't want it generating piles of metal and
drilling into the bolt, anyway - all it needs to do is bite and draw the
bolt out.

Maybe I'll give it a try - I think I've got a few broken bits somewhere.

Always wondered if there's a good reason why normal bits drill in the
same direction as screw threads, or whether it's it just cooincidence...
