Title: Almost worthless....
Review: Back in the day I had a tapcon bit that had the drill bit and the sleeve all in one piece. This product is just a metal tube that slides over the drill bit that must be secured to the base with an allen screw. So, you've got to have the base, an allen wrench, special tapcon bit (marketing genuis!), the metal tube, and the phillips bit; something's just begging to get lost. The base did not fit into my 3/8" hammer drill (said it would, but it didn't). Then when I finally drilled the hole - in brick - and tried to drive the tapcon screw it didn't secure at all! I could just pull it out. Yep, used the correct sized bit.Tapcon used to be the honey. I don't know what happened.
