This core bit is absolutely amazing at cutting through reinforced concrete. Some choose to use this core exclusively as a rebar cutter because of how well it cuts through rebar wet or dry with no mess. With a barrel length of 12″ overall and a 9″ cutting length this makes it one of our most versatile bits we carry. Great for radon mitigation and other routine coring jobs.

These are heavy duty core bits designed to be run wet or dry. No more messy slurry in a clients basement or on the job site. Able to withstand very high temperatures and maintain strength for a long life of dry or wet cutting. Using water will extend the life if available. Specially formulated high quality diamond segments, provide fast cutting and a long life in a variety of materials including concrete, reinforced concrete with rebar in the line, brick, block and masonry.

Works on your tools without hassle.
This premium dry diamond core bit is built with a universal 5/8″-11 threaded arbor, meaning it screws directly onto most variable-speed angle grinders and many compact coring drills with no adapter required. If you’ve got a DeWalt, Makita, Milwaukee, Bosch, or Metabo grinder, you’re ready to core reinforced concrete, block, brick, or rebar straight out of the box—just set your tool to rotary-only mode.

Unlock even more versatility with an adapter.
Pair it with one of our 5/8″-11 adapters and this bit expands to nearly every drilling platform in the field. Drop it into a standard 1/2″ drill, run it on an SDS-Plus rotary hammer, or harness the torque of an SDS-Max machine—all while keeping it in rotary mode. Whether you want the convenience of a grinder or the power of a rotary hammer, this core bit adapts to your setup and keeps cutting fast and clean.
