Core drill bits are heavy-duty, hollow-centred cutting accessories designed to bore large-diameter holes through masonry, brick, blockwork, and concrete.

Diamond core drill bits feature industrial diamond grit embedded in the cutting edge - allowing you to grind cleanly through hard stone and brickwork without shattering the substrate. Meanwhile, Tungsten carbide-tipped (TCT) core bits tackle tough building materials - letting you create precise openings for waste pipes, boiler flues, and extractor fan ventilation.

The hollow cylindrical design removes a solid core of material rather than pulverising the entire hole, reducing friction and significantly increasing your drilling speed. Slotted dry core bits allow dust to escape during operation - keeping the cutting path clear when working indoors.

Complete your setup with reliable diamond core drill sets and accessories from trusted brands like Mexco, Toolpak, and Spectrum.
