Diamond Core Bits

Learn more about diamond core bits

A diamond core bit is a hollow bit tipped with diamond, used to grind out a ring of hard material and leave a cored hole. That makes it suitable for concrete, brick, granite and porcelain.

Travis Perkins brings product expertise and reliable stock availability, so you can compare the product specifications and choose the right bit for the job.

Typical uses

• Drilling service penetrations through concrete and brick for pipes, cables and ducting.

• Creating cored openings in granite and stone where a clean edge matters.

• Forming holes in tiles, including porcelain tiles, and slabs where the right bit and technique help control chipping.

• Wet drilling in masonry and stone where cooling is needed.

• Dry drilling where water cannot be used, often for shorter or handheld work.

How to choose the right diamond core bits

• The right choice starts with the finished hole size, the substrate and the drilling method.

• Choose by the finished hole diameter you need, then check the product specifications for substrate, wet or dry use and compatibility with your core drill.

• Make sure the bit matches your core drill, including shank type, thread and arbor. For larger cores, a stand mounted core drill can give you more stability and control.

• If you are drilling reinforced concrete, confirm the bit is rated for rebar. The product page should also show whether it is suitable for concrete, brick, granite or porcelain.

• Check the product specifications before you order so you know the bit suits the job and the method you plan to use.
