Core & Diamond Core Bits & Accessories

Core bits cut cylindrical holes in concrete, masonry and tile.  Diamond core bits use embedded industrial diamonds to grind through hard materials while producing minimal dust.

What are core and diamond core bits used for?
Core bits are designed to drill large, clean holes by removing a core of material rather than pulverizing the entire area. They’re used for:

  • Concrete, brick, block, and masonry

  • Ceramic tiles, granite, and marble (with diamond-tipped versions)

  • Creating access points for plumbing, electrical conduits, HVAC ducts, and extractor fans
    Diamond core bits are ideal for hard, abrasive materials and offer precision with minimal vibration.

What’s the difference between dry and wet diamond core bits?

  • Dry core bits are used with standard rotary drills and are often vacuum brazed or laser-welded, designed for materials like brick or block without water cooling

  • Wet core bits use water as a coolant and dust suppressor, ideal for reinforced concrete, granite, and tile, and require slower RPM tools like rotary drills or rigs
    Using the correct type extends tool life, improves efficiency, and protects the material from cracking due to overheating.

What should I consider when choosing a core bit?

  • Diameter and depth – match the size to your application (e.g. 25 mm–150 mm for plumbing/electrical work)

  • Connection type – SDS-Plus, SDS-Max, or ½″ BSP threads depending on your drill

  • Material type –

    • Segmented diamond bits for concrete and stone

    • Continuous rim bits for tile and ceramics (smoother edges)

    • Tungsten carbide core bits for general masonry
      Always check your drill’s power and clutch rating; core bits should be used with high-torque, low-speed drills, preferably with safety clutches.
