I think your spell checker turned fluted into flights. But no matter. A wood screw's flutes probably would tend to lift chips and debris - as long as it was turning clockwise viewed from the top.
A post hole auger is kinda like a large wood screw, watch the following video - the tractor not the guy in front. Now imagine if the auger was turning the opposite direction - do you think it would it work as well?
