Round- and Hex-Shank Masonry Drill Bits for Hammer Drills
Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. These bits drill faster and penetrate materials with less pressure than rotary-only bits. Also known as percussion or impact bits.
Serrated-point drill bits deliver faster, cooler cutting as well as longer life than standard-point masonry drill bits.

Tapered-Round-Shank Masonry Drill Bits for Rotary Hammers
Also known as A-taper bits, these fit rotary hammers with a taper-shank chuck. Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. This type of bit drills faster and penetrates material with less pressure than rotary-only bits. Also called percussion or impact bits.

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.

Chip-Clearing Round-Shank Masonry Drill Bit Sets for Rotary Hammers
A more controlled chip removal reduces heat buildup, making these bits good for use on brittle material such as block and brick. Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. This type of bit drills faster and penetrates material with less pressure than rotary-only bits. Also called percussion or impact bits.

Extensions for Round-Shank Drill Bits
Attach to the shank of a drill bit to extend its reach.
To attach two-piece extensions, insert a drill bit into the collet, then thread the collet onto the extension and tighten with a wrench.
