This extension bit is of really great quality steel construction - no surprise from a company with a great reputation from making quality tools. This has precise tight fit to bits where you can trust no wiggle room when fitting them to your drill or to bits. Though a minor issue, it would be nice for it to have a marker or label etched into the bit that states its dimensions 3/8" x 12".

Rated 1 out of 5 by from I tried to use this with a door lock bit/saw... I tried to use this with a door lock bit/saw for cutting a 2” hole through a wall. The set screw doesn’t grip well enough and ended up grinding the shank of the drill bit in the center of the hole saw. The design just isn’t very good unless the bit being put into the extension has a 3/8 in shank.
