Abracs Dry Diamond Core Bits are circular, rimmed drilling tools designed to cut precise holes through masonry, tile, brick, block and concrete without the need for water. They are primarily used with handheld angle grinders or dedicated core drills to create service penetrations for pipework, electrical conduit, box cut-outs and tiling fixtures where dry cutting is preferred or wet cooling is impractical.

Each core bit consists of a high‑grade steel barrel with sintered industrial diamond segments brazed to the cutting rim. The segmented rim profile provides efficient air cooling and dust clearance during dry operation, while the steel body is given an anti‑corrosive finish to resist rust in jobsite conditions. Typical thread fittings include M14 (ISO metric) for European angle grinders and, where specified, 1/2"-20 UNF or arbour adaptors for use with drill chucks; please check the arbor thread before ordering. The product conforms to commonly accepted ISO/EN thread standards for tool arbors and is manufactured to abrasive industry tolerances for concentricity and run‑out to reduce vibration and improve cut quality.

These bits are available in a wide range of diameters and segment profiles to suit different materials and cutting depths. The diamond grit grade and segment bond are selected to balance life and cutting speed on abrasive materials; harder bonds with finer grit are used for highly abrasive masonry while softer bonds with coarser grit will cut faster on dense concrete. Dry core bits are designed for intermittent operation to avoid overheating; segmented rims help maintain cutting performance and extend service life.

Typical users include electricians, plumbers, tilers, building contractors, glazing installers and M&E engineers. Industries that commonly use Abracs Dry Diamond Core Bits include construction and refurbishment, utilities and mechanical services, and specialist fit‑out contractors where fast, dust‑managed hole cutting is required. Key benefits are extended life from industrial diamond segments, effective corrosion resistance from the treated steel barrel, compatibility with standard M14 arbors and the ability to cut dry where water cooling is not available.
