Works great
Had to drill four holes in porcelain tile to mount a toilet flange you need to start at a 45 degree angle then gradually bring it straight up, only drill for about ten seconds at a time then spray the bit and hole with water. Each hole took about five minutes. One bit did four holes no problem.

    Cut holes for dishwasher mounting holes.
    Cut granite worked like it should used water to keep cool. Worked better then expected.

    Takes a loonnnggg time
    Took 30-45 min. each hole. After 4 the saw is worn down. Will need another for the other 4 holes. Not happy about that. We kept it wet and oscillated as we drilled. The porcelain tile is 5/16” thick & tough as nails! Finished holes look really nice.

      The Best
      I drilled 8 holes in porcelain tiles and it was super easy.My son was constantly spraying cold water on it and I was cleaning it out every 5 seconds.Make sure drill is at slow speed with moderate pressure. Keep it cool and cleaned.

        I drilled 8 holes through tile and didn’t crack a single one, couldn’t be happier! There isn’t much, that’s more stressful than doing a tiling job, and then needing to drill through that tile! Would buy several times over!
          Worked perfectly
          I bought this to drill holes on a soap dish to prevent water from puddling. Worked perfectly. I poured water in the dish and started at a 45 deg angle and then went up to 90 deg while rocking side to side. The hardest part was to get it to stay in one place at the start. I held the drill bit end in one hand and used the the other hand to power the driver which helped stabilize it. Also, I drilled at low speeds (like a 5 or something on my Dewalt). Also dipped the tip in water after each hole. Came out perfect for my purpose. Only dislike is the red coating comes off instantly so it should've been left un-painted at the tip.

            Awesome for Fireclay Sink
            I used this bit for a reverse osmosis faucet to add on to our fireclay sink. I cut the hole before the sink install. It worked like a charm. I sprayed some water a couple times and cleared out some of the debris as it cut. It cut through about 5/8" very smoothly. The hardest part was seating the cut at the very beginning, but if you start at a 45 degree angle like the video suggests then you should be good. I rotated it like the video showed as well. I would definitely purchase this and use it again if I ever had a need.

              If you're making holes in tile, this is it. Different sides for different applications. Don't forget to use a lubricant even if it's just a bottle of water

              Works perfectly!
              Purchased the 3/16th and it was easy to use to cut through ceramic stoneware. Used some water while drilling and it worked like a charm.

                Does not last at all
                Bought it to drill porcelain tiles. Tested on ceramic, drilled one hole then used my regular drill bit to save it for the real job. Can't finish a porcelain tile, half way through. Water and circular motion don't help.
