Abracs Dry Diamond Core Bits are cylindrical cutting tools fitted with industrial diamond segments for dry coring of masonry, brick, block, concrete and natural stone. Designed to cut precise circular holes for pipework, ducts, conduit, sockets and inspection ports without the need for water cooling, these core bits are the choice when mobility and on‑site convenience are required.

The core bits consist of a steel body with sintered diamond grit segments bonded around the cutting rim. Typical bond hardness for the Abracs range is a medium-to-hard matrix to suit general-purpose masonry and concrete use; the bodies are finished with a protective powder coat to resist corrosion. Abracs Dry Diamond Core Bits are supplied to fit common power tool arbors, with M14 thread for European angle grinders and can be supplied with adapters for imperial 5/8"-11 or SDS connections where required. Segment types include segmented rim for rapid cutting and dust clearance and turbo rim for faster, smoother cuts. Manufactured under ISO 9001 quality control systems and produced to recognised EN/ISO/DIN design practices for diamond tools, each bit is balanced for rotational running to minimise vibration and wear.

These core bits are typically used by installers, electricians, plumbers, HVAC engineers, utility contractors and general building trades when drilling service penetrations through floors, walls and precast panels. They are particularly useful on sites where water supply is limited or where wet cutting would create contamination risks. Typical applications include cable and pipe entry holes, socket recesses, sample coring and chasing for mechanical services.

Key benefits include long tool life from the sintered diamond segments, consistent hole accuracy and reduced chipping on most masonry substrates. The powder-coated steel body provides improved corrosion resistance in storage and on site, while the range of available thread arbors and adapters makes the bits compatible with a wide variety of handheld and rig-mounted power tools. Dry cutting removes the need for water management but does require appropriate dust extraction and PPE for operator safety.
