Bright Ideas - Diamond Drill Bits

An electroplated diamond hole saw with gritted edges is ideal for cutting holes into hard materials such as stone, marble and granite. Can also be used for cutting through porcelain, ceramic, quarry tiles, glass etc.

How to Use:

  • Always use a slow drilling speed. A hand drill is preferable or a variable speed power drill.
  • Keep the diamond tip and workpiece cool using water.
