  • 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.

    These drill bits work perfect for making holes in sea glass. I tried diamond tip bits but was not able to go through the glass without the glass breaking.
