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-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 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.

Hex-Shank Masonry Core Drill Bits for Rotary-Only Drilling
These hollow bits cut with their outside edge for drilling large holes. Instead of using a hammering action to break up masonry material, these bits drill with rotary action only, requiring more pressure to grind up material. Use with handheld power drills, drill presses, and in hammer drills set to rotary-only mode. Do not use in hammering applications. To achieve maximum drilling depth, break up and remove the core every 4” before drilling deeper.
