This diamond-impregnated core-style bit features superior long life and is ideal for drilling in both flat and contoured surfaces. Diamond grit a full 360-degrees around the circumference of the bit allows it to be used in a rasping action to enlarge a hole if needed. Holes on the side of the bit allow the removal of glass dust from inside the bit. For use on glass, ceramic wall tile, glass block, glass bottles, jewelry.

This 1/8″ dia. diamond core drill worked perfectly, using a hand held variable speed Dremel Grinder operating at the mid-range RPM. The kiln fired glass artwork was submerged under water. Start the hole with the grinder and diamond drill at a 30 to 45 degree angle to break the glaze surface and then position the Dremel/diamond drill perpendicular to the work surface. The end results was excellent.

I slumped some glass jars and drilled holes in them this afternoon. I was able to drill 12 1/2 holes before changing the bit. using my cordless Dremel tool, I created a cut in the glass for the hole, I held my drill at straight up and submerged each of the pieces into water and drilled through one piece at a time to finish.

I have never been very successful at drilling glass; however, this bit has done the trick. I build wind chimes and use old abandoned glass insulators as the striker. In order to properly use the insulators, I must drill a small hole through the center so I can suspend the wind catcher. This drill bit has been successful where others have failed. I have drilled several insulators and it seems as new as ever.

This is a good diamond bit for use in a Dremel tool. It’s not the fastest cutting bit I’ve used, but using the included cutting oil helps a little. I actually found it worked better with my drill so I could put more pressure on it. I had to cut 6 holes in ceramic wall tiles and needed them to be a little bigger than it’s 1/8″ diameter and the nice thing about diamond bits that have lots of diamond around the shaft is you can wobble it to make thew hole a little bigger.
