I got these drill bits to drill holes in the bottom of glass vases and plates. After shattering a lot of glass and destroying a few bits I finally realized that I was using them incorrectly. I added a little water to the vase bases to cool and lubricate the bit and they cut through the glass quickly and easily! I haven't used them to cut any other substances but I highly recommend them for glass.

I used the 1 1/4" diamond hole saw in concert with the Moen SecureAnchor system to install a grab bar in a tiled bath area. Followed the instructions and the job went quickly and cleanly. It did not disturb the tile area outside the hole. Easy to clean up with water and and old toothbrush. Looks like the hole saw will last for many many holes. Pleased.

I love these! I used them to put drainage holes in my planters, now I can pick out any cute pots I want without having to be disappointed when they don’t have drainage holes! Well worth the $$, easy to use, only takes about a minute to put a hole through plastic, ceramic, terra cotta. I haven’t had anything crack or break, and I’ve used it on >20 pots so far.

if you are drilling through 3/8"-1/2" ceramic tiles these bits wont last long. I would estimate at most 1.5-2 holes per bit. I had to drill 4 holes ....used all 5 bits. Cutting strength diminishes pretty quickly; however they did the "one time" job and for the price worked OK.

I bought these to drill holes in porcelain plates to make tiered cake stands. You definitely need these diamond-coated drill bits to drill porcelain - I tried carbide tips, and they took FOREVER and then cracked my plate at the last minute. These work much better and get through the plates cleanly and in a reasonable amount of time. Use water on the surface you are cutting. I'm really surprised at the variable quality. With the first four tips in the packet, I was able to drill 1-2 plates before the coating wore off the tip. Oddly, the last one has cut four plates and still looks almost new. Not sure why they were so variable and too bad they could not all be more durable, since it does feel wasteful to only be able to drill 1-2 plates with the other bits.

Figured if I used all the bits to get through the porcelain tile it would be fine. I only used 2 bits but probably could have used just one. They absolutely live up to the decription. Even appreciated the depth markings to be sure I got through the tile and backer board.They come in a handy plastic case. Just follow the reviews here or watch YouTube videos on how to use a diamond bit. I taped the tile to keep the bit from walking, started slow at a 45 degree angle, then straighten and occasionally dipped in water. I also taped a baggie under the hole to catch the dust. The bits are well marked, durable, get the job done and no hype. You won't be disappointed - great price too!
