- Drill holes in both flat and contoured glass
- Diamond-impregnated cutting bit for long life
- 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.

Worked great for drilling vent holes on a glazed bowl to be used as a slumping mold.

These were pretty good. I purchased 2 packs of 5..and 3 did not work, but they were certainly better than those multipacks of disappointments available from that Aword company. I am going to purchase more.

A few of the bits did not work well in drilling my glass. Two pieces actually cracked. I have ordered these many times before and this was the first time I had an issue
