Bob, Running in reverse would LIFT the chips up, but the screw wouldn't self feed into the chips.

"Lift" meaning chips/strings unscrewing themselves out of the hole? Probably so. I was thinking about a left-handed screw biting screw into the mess and unscrewing it. Instead of a right-hand screw running backward to unscrew the mess, how about something like a phillips screwdriver bit or maybe a drill blank with a left-hand drill type tip or spade tip ground into it?
