Diamond Drill Bits - 6 Pcs Set, 6mm-12mm, for Granite, Marble, Tile, Glass & Hard Materials, Round Shank, Dry Drill Bits

Very sceptical as I have had issues in the past drilling through porcelain tiles. To date I have used 1 x 6mm bit to drill 3 holes the 10mm for 4 holes and the 8mm for 1 hole and so far bloody fantastic considering the price.

I had to drill 6 holes in a wall covered with hard ceramic tiles, and used several drill bits, from Bosch to Dewalt, I must say these little diamond drill bits have been saving the tiles from cracks and made the difference. Would you need different types of drill bits? Yes, the product is good for refining the edges of the hole and helping remove material from the edge of the hole, but it's not enough to drill the whole hole. Would I recommend this product? Using drill bits for walls or glass doesn't provide a clean result like diamond drill bits, so yes!

I wasn’t expecting a great deal from these as they were inexpensive, but they pleasantly surprised me. The quality was far superior to my slightly dubiousness. As long as you keep your speed fairly low and lubricate with either a little WD40 or if cutting porcelains, I use water, the durability is excellent. I don’t think that these would stand up to high speed and they are far less liable to wander at a lower speed too. They give a nice round hole which is surprisingly accurate and the diamond coating has stayed sharper than I would have initially thought. Keep the speed down, keep the diamond tip fairly cool and these will do quite a bit of service. Extremely good value.

After a recent bathroom renovation I was dreading the part where I had to drill through brand new beautiful porcelain tiles just to hang a toilet roll holder, or mirror etc. The requirements are very different to drilling though the old ceramic tiles where a run of the mill masonry bit would do the trick. I'd watched videos, read articles and priced up the gear and still wasn't that confident. Having read the reviews for these drill bits I decided to get them and I'm glad I did. I only needed the 10mm and 8mm bits for my jobs but some high street places where selling single bits for £20+. Given the short life expectency of these types of bits I wasn't going to spend that sort of money. These bits are more than worthy of the positive reviews they've got. Combined with a suction drilling guide I got my jobs done quickly and with relatively little stress. Highly recommend.

After spending 30 minutes trying to drill a hole in a porcelain tile late at night, I decided to go on Amazon and get some diamond drill bits. It arrived the next morning and the whole set was way cheaper than in any of the other stores. All the bits were packed individually and they seemed great quality. Put them in my wireless drill and off I went to the bathroom to drill 2 holes. Started at a 45 degree angle and at a slow speed. Not even a minute and I have drilled through 11mm porcelain tile. In summary, amazing drill bits and did exactly what promised.

Ordered these to cut some holes in thick bathroom tiles. Unfortunately the ends of the drill bits blunted very quickly. I only managed to get 2 holes done by destroying 3 drill bits. Whilst they were cheap and did somewhat the job, they didn't last. No instructions came for me to do anything different with them, so can only assume they're poor quality. But they got some of the job done, hence the generous review.

This cut through the quartz quite easily but the offcut of the quartz remained in the drill bit and was unable to remove it. So only managed one hole use out of it

On first inspection the drills looked to be of very high quality. I was right to be impressed as they made very easy work of the ceramic pot. See the before and after pictures, three holes drilled without any hassle. It's important to follow the instructions, start slowly at a 45degree angle then bring the drill vertical to finish. What was unknown for me was just how thick was the base. I kept steady pressure, not too much required as the drill went through very easily. Only one job so far, but because of the quality, I can se these lasting for years.
