Extended-Length Carbide-Tipped Drill Bits with Coolant Holes
Also known as gun drills, use these bits to drill long, straight holes. A hole in the bit allows coolant to be channeled through the tool for more efficient chip evacuation. More wear resistant than cobalt steel and high-speed steel, these carbide-tipped bits maintain a sharper, harder edge at high temperatures for excellent performance on abrasive material.

SDS-Max-Shank Masonry Drill Bits for Rotary Hammers
The SDS-Max shank has three deep slots and two shallow slots for use with SDS-Max-drive rotary hammers. These bits cannot be used with SDS-Plus-drive rotary hammers. 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 known as percussion or impact bits.
Multi-point drill bits have five carbide points on the tip, which provide longer life and reduce vibration for drilling smoother, rounder holes than standard-point masonry drill bits.

SDS-Max-Shank Masonry Core Drill Bits for Rotary Hammers
These hollow bits cut with their outside edge for drilling large holes. The SDS-Max shank has three deep slots and two shallow slots for use with SDS-Max-drive rotary hammers. They cannot be used with SDS-Plus-drive rotary hammers. 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 known as percussion or impact bits. The included pilot drill makes starting holes easier.

Spline-Shank Masonry Drill Bits for Rotary Hammers
The shank has 12 splines for use with a spline-drive rotary hammer. Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules. These bits drill faster and penetrate material with less pressure than rotary-only bits. Also called percussion or impact bits.
Multi-point drill bits have five carbide points on the tip, which provide longer life and reduce vibration for drilling smoother, rounder holes than standard-point masonry drill bits.
