Hex-Shank Masonry Drill Bits for Tapping Screw Installation
Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks. Each is precisely sized to match the tolerances necessary to achieve maximum holding strength from tapping screws. They have a built-in hex collar that acts as a stop for repeatable drilling depths. The split point keeps the bit centered without a pilot hole.
A drive sleeve (sold separately) slides over the drill bit to drive fasteners without removing the drill bit from the tool. One end engages with the hex-collar on the drill bit, while the other end holds a screwdriver bit.
