Description
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.

So far, I drilled 8 holes with one bit and I’m happy with the results. It looks like I can do I or 2 more and it will be dull. I did use cutting oil and a slow speed. I cut holes in the sides of glass votive holders, so driving on a convex surface is more difficult. I may try to cut the bit past the dull part with my Dremel to see if I can get more holes out of it. Will let you know. $3.00 v the $11.00 Dremel bit, I think this one wins!

Used these in my drill press to drill porcelain tiles for my wife who made Christmas decoration out of them. Spraying with water, they worked great!
