Hex-Shank Masonry Drill Bits for Impact Drivers
The 1/4" hex shank allows these bits to be used with standard impact drivers. Instead of using a hammering action to break up masonry material, they drill with rotary action only, requiring more pressure to grind up material.

Hex-Shank Masonry Core Drill Bits for Rotary-Only Drilling
These hollow bits cut with their outside edge for drilling large holes. Instead of using a hammering action to break up masonry material, these bits drill with rotary action only, requiring more pressure to grind up material. Use with handheld power drills, drill presses, and in hammer drills set to rotary-only mode. Do not use in hammering applications. To achieve maximum drilling depth, break up and remove the core every 4” before drilling deeper.

Drive Sleeves for Hex-Shank Masonry
Drill Bits for Tapping Screw Installation
Drive a tapping screw without removing the drill bit from your impact driver. One end engages with the hex-collar on the drill bit, while the other end holds a screwdriver bit.

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.
