I was at Lowes yesterday, and I saw that Greenlee has been making some changes to their line ...
While not the exact bits discussed by this thread, I did see some Greenlee augers that were quite short - maybe 6" OAL- and that had 1/4" hex shanks. This would make them suitable for use in impact drivers, and a direct competitor to the Irwin Speed-bor Max (with which I've had great success).
