Abracs Dry Diamond Core Bits are rotating cutting tools designed to cut precise circular holes in masonry substrates without the need for water cooling. They are intended primarily for dry coring of concrete, brick, block, natural stone and ceramic tile when access to water is limited or when a dry workflow is preferred, for example when working indoors or on finishing tasks.

Each core bit features a hardened steel body with sintered diamond segments on the cutting rim. The diamond grit is bonded to the segments through a high-temperature sintering process to provide consistent wear rate and prolonged life on abrasive materials. The body is typically supplied with a corrosion-resistant plated finish and manufactured from quenched and tempered carbon steel equivalent to C45 for strength and dimensional stability. Abracs Dry Diamond Core Bits are produced under an ISO-managed quality system and are made to conform with common DIN/ISO/BS dimensional and thread conventions applicable to power-tool accessories.

These bits are available with common arbour/drive options to suit UK tools, including M14 thread for angle grinders and threaded mandrel or SDS-plus-compatible arbour options for rotary hammers and drill drivers (select the arbor type to match your tool). Cutting rim styles include segmented or turbo-segmented profiles optimised for dry cutting to minimise heat build-up and dust chipping; they must be used with the correct rotation speed and intermittent drilling to avoid overheating.

Typical applications include installation of service penetrations for plumbing and electrical work, anchoring and pipework entry points on construction sites, HVAC and M&E installations, and tile and stone trade work where neat, chip-free openings are required. Industries that commonly use these cores are building and civil engineering, utilities, plumbing and heating, tiling and flooring, and maintenance departments.

Key benefits are the cutting efficiency and long life of diamond abrasives, lower risk of segment glazing with the dry-segment profile, the mechanical strength of a hardened steel body and a corrosion-resistant finish for extended storage life. Compatibility with standard arbors and thread types makes these bits easy to fit to a range of power tools; proper use with appropriate speed and dust control will maximise service life.
