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.
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.

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.

SDS-Plus-Shank Masonry Drill Bits for Rebar-Cutting
When you encounter rebar, stop drilling and mount one of these bits in your tool. Drill through the rebar, and then resume drilling with your masonry drill bit. The SDS-Plus shank has two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers set to rotary-only mode. These bits cannot be used with SDS-Max-drive rotary hammers. Do not use in hammering applications.

Replaceable Carbide-Insert Drill Bits
Use these bits to drill a large number of holes with high precision. When the cutting edges dull, replace the carbide inserts (sold separately) instead of the entire bit. Each drill bit requires two inserts—one on the inner cutting edge and one on the outer cutting edge. Bits can be used in CNC machines with coolant-through technology; holes in the bit allow coolant to be channeled through the tool for more efficient chip evacuation.
