SKU: 1.2mm Diamond Drill Bit Set - Dremel Size Category:


These diamond-impregnated 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.

    Great products, even better prices!!!!

  2. Sergio (verified owner)

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

  3. Dalene Bradshaw (verified owner)

    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.

      Sorry about that. We test each bit but may have missed one. Remind me on your next order and we will give you replacements.

    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
