Extended-Length Chip-Clearing Drill Bits
Access hard-to-reach spots and drill deep holes. Parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow. The split point keeps the bit centered without a pilot hole.

SDS-Plus-Shank Masonry Drill Bits for Rotary Hammers
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. 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.

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.

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.
