The Abracs Dry Diamond Core Bit (ABDC065) is a 65 mm diameter dry-cutting core bit designed to bore clean, accurately sized holes through masonry materials such as concrete, brick, block, tile and natural stone. Its primary use is rapid hole-making for services and fixings where water cooling is impractical or site conditions demand dry cutting, for example electrical conduit, plumbing routes and anchor installation.

Technically, the ABDC065 comprises industrial-grade diamond grit embedded in sintered metal bond segments that are brazed to a high‑strength steel core barrel. The segment height and bond formulation provide an effective balance of cut rate and life on mixed masonry. The steel barrel carries a corrosion‑resistant finish to reduce surface rust during storage and site use. These bits are produced under ISO 9001 quality management systems and are manufactured to meet relevant abrasive tool safety requirements such as BS EN 12413 where applicable; customers should follow machine and PPE guidance for dry cutting tools.

The ABDC065 is supplied for use with standard core bit arbors and drill adaptors; many Abracs dry core bits are compatible with common thread/arbor interfaces (for example M16 or 5/8"-11) – check the product code or arbor supplied for the specific thread on your order. The head type is a segmented rim/core barrel designed for rapid dust clearance and reduced load; the drive interface is via the arbor rather than a directly driven shank.

Typical applications include trades and industries such as building and construction, utilities, HVAC and plumbing installation, electrical fit‑outs, tiling and renovation/heritage masonry work. The key benefits of the Abracs Dry Diamond Core Bit are example‑specific: the sintered diamond segments provide long life and consistent cutting speed across abrasive materials, the treated steel core gives improved corrosion resistance during storage, and compatibility with standard arbors makes it easy to fit to common drills and angle grinders. Dry cutting eliminates the need for water in many situations, though dust control and intermittent operation are essential to avoid overheating.
