SKU: 1.6 mm Diamond Bit Set - 5 piece Category:


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. 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
  • 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.

  1. GlassWench Studio (verified owner)

    surprised to see that I am the only one having an issue with this bit. I was able to drill 4 holes in waterglass before the bit was unusable. tried a second bit, thinking it might be just the one. same result. same result on the 3rd bit. I’ve used the 3mm and gotten 30+ holes out of it, in all kinds of glass including opaques. not a fan, at all.

      I would guess that the drill was spinning too fast and not getting enough water around the bit and shortening the
      bit’s life. The diamond drill bits need to cooled by water while you are drilling.

    Product was of good quality. Shipping was very slow due to a vendor show the company attended.

      Sorry about the delayed shipping. We generally ship same day but because we were at the Glass & Bead Expo in Las Vegas we weren’t at the the store. We teach there and exhibit as well. We do appreciate your business.

    You get what you pay for. $5 was a fair price although the shipping was expensive.
