Core Drill Bits

Shop core drill bits at Betontools for concrete, masonry, tile and stone applications, with material suitability depending on the bit selected. Browse wet and dry diamond core bits, masonry core drills, tile holesaws and drilling accessories from brands including Klingspor, OX, ARIX, ARMEG, Thor Tools, Mexco and Distar.

Choose the right bit for the material

  • Concrete and reinforced concrete: select a diamond core bit specifically listed for your material and drilling setup. Check the recommended wet or dry method.
  • Brick and masonry: compare dry diamond and TCT masonry core options against the exact material, drill requirements and intended hole size.
  • Tile and stone: match the bit to ceramic, porcelain or the specific stone being drilled. Check whether it is designed for a drill, angle grinder or another machine.
  • Specialist accessories: mortar-raking and finger-milling bits perform different jobs from core bits. Check their stated purpose before ordering.

Check size and machine compatibility

  • Confirm the required hole diameter and usable drilling depth, not just the overall barrel length.
  • Match the spindle thread or shank to your machine. Listings include connections such as 1¼ UNC, ½ BSP, M14, M16, hex and SDS adaptors; these are not automatically interchangeable.
  • Check the bit's permitted speed, operating mode and the machine's drilling capacity. Follow the specific product instructions rather than assuming hammer action is suitable.
  • Check water supply, cooling or dust extraction requirements and the accessories supplied with each bit or kit.
  • Adaptors, extensions, pilot drills, guide rods and slurry-control accessories are separate listings unless expressly included.

Complete your drilling setup

Compare core drill machines, core drill rig motors and core drill stands, or browse the wider core drilling equipment range.

Need help selecting a bit or adaptor? Call Betontools on 1800 238 668 with your material, required hole diameter and depth, and machine model or spindle connection.
