Diamond Drill Bit, 10 pcs Glass Diamond Hole Saw Set Drill Bits Extractor Remover Tools for Ceramics, Porcelain, Ceramic Tile 6mm - 30mm

I have only used the biggest one so far, but the quality for the price is awesome. So far I only made a couple of holes and it worked really well, no effort on porcelain tile which has been always my least favorite. Only thing I would add is a way to center the piece so damaging the tile could be avoided for sure. Anyway 9,99999 out of 10.

These worked perfect for what I needed them for. They were easy to use. I had some terracotta pots (craft projects) I needed holes cut into and these did the job! Not one pot broke while making the holes.

I needed these diamond drill bits for drilling holes in tile during a bathroom shower remodel. They were much cheaper than buying locally, and they got the job done. The quality isn’t the highest, so I wouldn’t count on long-term repeated use, but for a one-time project, they’re a great budget-friendly option.

I bought these along with ADA grab bars to install in a walk in shower. These diamond drill bits made drilling the holes through the tile the easiest part of the job. They really should come with instructions or cautions that they need to be run with a constant water bath. With water to cool and flush away debris they cut through porcelain tile like a hot knife thru butter. If you run them dry they will burn off the diamond coating in a second or two.

I used one of my drill bits today to cut a hole into wine bottles to make into lamps! Worked PERFECT!! I had watched several "how to" videos on YouTube on how, but, these drill bits are great!

I used these bits to drill drainage holes in my ceramic pots and I was successful with all three! First, I added water as I drilled into the pot at an angle to give it a pocket to hold on to, and then as the bit became more a long the way, I straightened out the bit and gave it a little pressure to get through. Do be careful with apply too much pressure towards the end because you could possibly "punch" the pot and crack it. Other than that, it took me about 5 minutes with each hole or less and I was on my way to putting plants in them. Overall, satisfied!

Had to drill into a tile wall to hang a very heavy mirror. I needed a sizable hole to install a certain kind of wall anchor and did not want to use a carbide bit for fear of damaging the tile or even getting the bit started, so looked into these. The whole set cost less than one bit at HD and worked flawlessly. Make certain you keep the bit cooled with water, either spraying while drilling or stopping and cooling it in a bowl of water. Start the bit at perhaps a 45 degree angle to your project, be steady and you should get a perfect result. Very happy with my purchase. Just my humble opinion mindya! Moi

Just got these & used them for the first time. It worked out great for drilling holes in pots. The outside hole is perfect, the inside of the hole was a little wonky, but got the job done. I would order these again.

Worked well for cutting holes in ceramic tiles, a little awkward getting them to stop skating out of place but having an adjustable speed drill helped and a squirter water bottle to keep the bits cool while cutting, once you cut through the glaze it's real easy. Very pleased with them.

wow i could not believe for under $15 I got a set of these bits that work really well! i have used one of the bits to make holes in 2 ceramic glazed pots and 3 terra cotta pots and it is still in fairly good shape to do a few more. i would recommend for DIY and craft projects.

It does the job, but I'm wondering if it's just me or if the drill bit is burning out too quickly

Better than more expensive ones. Recommend this item

Used to make holes in my plant pots. Install on your drill and makes a nice hole. Just dont push hard, let the but do the work.
