What Customers Are Saying

This diamond-coated drill bit performs well for drilling holes in ceramic, glass, and tile materials, but requires careful technique. It works best with water to keep the bit cool and clear debris, though dry drilling is more difficult and can cause faster wear. The bit can be challenging to start and keep steady, especially on smooth surfaces, but using a jig or angling the bit initially can help. The bit's durability varies, with some customers reporting multiple uses and others finding it wore out or bent after just a few uses, particularly on thicker or harder materials. Overall, with the right technique and patience, this diamond bit can create clean, chip-free holes in a variety of ceramic and tile surfaces, though for more demanding applications, a higher-quality bit may be required.

Response from Team Kobalt

We would love to know some details on the material you were cutting so that we can better understand why our hole saw did not perform to your standar...

This bit wanders a lot, you have to really brace yourself and introduce it to the tile very slowly. I needed to drill 8 holes, it did 3 OK and barely got through the 4th. My wife used a spray bottle to keep the bit wet while I drilled. I will buy 2 more bits for the remaining 4 holes.

Good for Lowe’s

I used this once so far. It was to cut a hole in a wine glass. Used with water and a template I made to keep the bit steady due to no arbor. Worked great, let the drill do the work. No casualties.
