Patent Pending tooth set design optimized to remove material faster. Attached arbor and pilot drill included. New side slot increased leverage for faster, easier slug removal. New exterior red coating reduces side wall friction for efficient cutting. Heavy duty .050 side wall for greater stability.
I have an Irwin Quick Lok extension that works great with Lenox bits but not this one. This one pops up immediately. It's only a matter of time before he falls to the other side of the wall and I can't reach him. I'm returning it and buying a Lenox.
