Core Drill Bits for Masonry and Concrete

Remove a core of material with these hollow bits to make larger holes than fluted masonry bits. They're often used for installing pipe and conduit through brick and concrete. The carbide tip resists wear and heat to stay sharp.

SDS-Max Shank for Hammer and Rotary Drilling

SDS-Max

Shank

The slotted shank is compatible with SDS-Max-drive rotary hammers. These bits use simultaneous rotary and hammering action to penetrate material. Also known as percussion or impact bits.

Standard Point—The most common point type handles most jobs. However, for more aggressive cutting that generates a lot of heat, consider a multipoint or serrated bit.

Pilot Drills—Cut a groove before drilling to make starting the hole easier.

Changeable-Size Core Drill Bits for Masonry and Concrete

Instead of investing in multiple bits, change the bit body to drill a different-sized hole. These hollow bits remove a large core of material from concrete, brick, and masonry for installing pipe and conduit. The carbide tip resists wear and heat to stay sharp. Bits include a pilot drill to make starting holes easier.
