Worked really well on my granite countertop. We need the 1/2 inch bit to drill a hole for the RO faucet and this dry drill bit did not disappoint. I was able to drill a hole in 1 minute.Only issue is that I can't remove the piece of granite that is inside the bit after the job is done so, this means that even though the bit is still good, I can't reuse the bit anymore to create another hole.

I needed to drill two small holes into my newly installed tile shower wall to install a shower control unit. started with masonry bits and when this did not work I moved to a Bosch glass and tile 1/4" bit. Neither would do more than start a pilot hole. Used one of the 6 mm bits from this kit, working slowly and misting water on the tile as the bit moved through the tile. It took about a minute to walk through the tile but cut smoothly through both holes using just the one bit. I would recommend using the Bosch bits to start the hole since they have a point. Once you have established an indentation into the tile switch over to the diamond bits. Excellent product at a great price!

I had to learn to drill a hole in stone to get this right. After some missed queues I finally got it right. The diamond encrusted drill bits work well.

I used this to drill a hole in our quartz countertop for an extra faucet (we got a reverse osmosis water filtration system, which I also highly recommend.)I tried it at first without a jig and it was clear that was a bad idea so I used my portable drill guide. I was concerned about not being able to clamp the guide down but it wasn’t necessary. Just using that to keep it straight made it so that the hole was perfect.I used two bits to get all the way through the stone. It’s possible I could have done it with one but so much dust built up on the bit after about 2/3 of the thickness that I decided to switch. I also then added water. I’m not sure if that helped with cutting but it was getting EXTREMELY hot and was starting to smoke and it helped with that.The guide was one that’s listed on ace hardware for $43 but I’m certain I got it for less at harbor freight. You’ll definitely need one if you’re going through stone, especially if you want to preserve the finish of the stone, as it’ll jump around a ton.I did not use a hammer driver, as I wasn’t sure how that would go, so I just used my lil’ old battery powered Ryobi drill. I’d say it took about 2 min to get through 1.25” of quartz.

I have only used 2 of the 6mm I had to use Tapcon bits to start the hole as these walk all over the tile trying to get started, it took one and a half bits to mount 2 safety hand rails in my mothers shower. They did make a clean hole for the anchors once started.
