Round-Shank Masonry Drill Bits for Tapping Screw Installation
Each bit is precisely sized to match the tolerances necessary to achieve maximum holding strength from tapping screws. Use with handheld power drills, drill presses, and hammer drills. The shank has a tang which allows it to fit into a drill press with a tapered spindle.

SDS-Plus-Shank Masonry Drill Bits for Tapping Screw Installation
SDS-Plus Shank
Each bit is precisely sized to match the tolerances necessary to achieve maximum holding strength from tapping screws. The SDS-Plus shank has two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers. These bits cannot be used with SDS-Max-drive rotary hammers.

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.
