These diamond-impregnated drill bits features superior long life and is ideal for drilling in both flat and contoured surfaces. Diamond grit is a full 360-degrees around the the bit.  These bits can be used on glass, ceramic wall tile, glass block, glass bottles, and jewelry.

  • Drill holes in both flat and contoured glass
  • Diamond-impregnated cutting bit for long life
  • Slots on the side of the bit allow the removal of material
  • Ideal for decorative projects including glass blocks or glass bottles

The diameter listed is the size of the hole drilled. However, it is somewhat nominal due to the fact that the diamond grit is plated on the bit. Sometimes the layer is slightly thicker, as it wears, the size gets slightly smaller. Drilling technique can also be a factor, since you are really grinding, not drilling. Final hole size could vary perhaps + or – 1-1.5 mm overall with all the factors considered.

    I tried these tools on ceramic glaze and they did not work worth a D, was not what I was expecting. Will not ever purchase them again.

      While the diamond bits are recommended for drilling glass, the ceramic glazes can be tough to get through at times. The bits respond better if you’re drilling while wet. Not sure if this is what was the issue, but that would help. Also it is recommended to use these in a dremel rather than a cordless drill.
