- 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.

I still have the occasional bit that doesn’t work out, but these bits are the best I have found by a lot. At $1 each, the value is solid. I drill glass for hours a day at times and while I don’t count for each bit, I feel like I average 500+ holes/bit consistently. Some of these bits go on forever and exceed that average significantly. I rarely have glass break while drilling.
The Glass House has offered to replace those bits that don’t work, but it doesn’t happen often enough for me to pursue. The value is still excellent with those Occasional losses. I only mention this to highlight their excellent customer service. Thanks Glass House, you’re precision product allows me to make a living doing what I love. No pressure 🙂
