This diamond-impregnated core-style drill bit 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. Slots on the side of the bit allow the removal of glass dust from inside 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.

    Bit worked perfectly to drill hole in bottom of ceramic tequila bottle. Price was about 3-5 times less expensive than others I found either at local stores or Online. Received within a few days along with communications from Marilyn on status of my order.

    Just finished using this on a couple of dinner plates to mount a candle holder and the finished product was superb, it drills perfectly. First time I’ve ever used one of these diamond bits. The seller was great too. Prompt service and very happy with the purchase.
