    Great drill bits for 1-2 holes in granite, don't expect perfection
  

*by R***N on Reviewed in the United States on August 17, 2020*

What you get is the same quality drill bits you get in the photos, so it's not the greatest quality, but for less than $10 shipped to my house in 1 day, this is value. I needed to drill 1 hole through my 1 1/8 inch granite countertop to install a Reverse Osmosis filter faucet, and I was able to drill 1 hole using 1 bit. The bit is a little worn, but still usable for a second hole. The bit was not perfectly center, so it danced a little, but my drill was not perfect either. I did slip a little while starting the drill hole at 45 degrees, but it wasn't a big deal with it being covered by the faucet. I recommend you practice on something first. The drilled hole was not perfectly straight due to the imperfection in the drill bit and my drill, but it was good enough and I wish I had done this sooner, but I didn't want to drill into my granite in fear of destroying my countertop. I did use my kids' putty to form a small pool of water to keep the drill cool, and I still had another bit as a backup in case the first one failed.Overall for my purpose of drilling a 3/4 in hole into a 1 1/8 inch granite, it worked well enough and now we have a good drinking water on the countertop. the granite core did crack while I was drilling, so I discard it and made it easier to finish the job. it was a quick 5 minute job for me and I am very proud of the outcome.

    Used to cut porcelain tile - won't cut cement board
  

*by D***D on Reviewed in the United States on November 19, 2020*

I used this Joiner 25mm diamond hole saw as part of a home project to cut some porcelain tile in one of my  bathrooms .This project started with needing to replace a Moen 1222 shower cartridge which required removing the retaining clip for the cartridge.  But, the plumbing had been installed deeper than the tile, and so I needed to cut some of the porcelain tile above the shower cartridge to remove the clip.I used a diamond wheel from another set with a Wren (Dremel-copy) tool to do the first set of linear cuts.  Because the wheels were not going to be able to easily join the cuts together, I decided to finish the cuts with some diamond hole saws.So, I finished the cuts with a Uxcell and Joiner 25 mm diamond hole cutter, with the Uxcell doing most of the cutting.  I switched to the Joiner mainly because the cutting seemed to slow down - as it turned out, this was because I had run into the cement board backing and these diamond cutters won't go through cement board.  But, removing the porcelain tile plugs created a deep enough inset to get to the Moen cartridge retaining clip, so I stopped there.  Probably I would have used a bimetal  hole saw cutter to go through the cement board backing had I needed to go deeper.Cutting porcelain tile is a slow and VERY dusty job - lots of fine dust gets thrown in the air.  You have to regularly irrigate the cut and the cutters with water otherwise the cutting stops because of the accumulated dust clogging up the fine diamonds.  I  wore safety glasses and an N95 dust mask, and also wrapped the Wren in a towel and kept my hands under the towel, mostly to protect the Wren and my hands from all the dust, but also in case any of the cutters broke off.  You don't want to get silicosis from breathing all that fine rock dust.The Uxcell and Joiner both worked fine for the porcelain tile - You have to start cutting at an angle to get the circular hole going.  Having some linear cuts already in the tile helped a lot, so if you have trouble getting the hole seated, it might help to use a diamond wheel to start a linear cut.Although the Joiner wheel did not do much cutting, I posted it with the Uxcell just to show the difference in the axles - the Joiner has two thicknesses of shafts - I'm not sure if that makes it stronger or weaker, since the thicker segment could make it stronger, but the transition point could be a weak point where the shaft breaks.

    A great tool!
  

*by S***D on Reviewed in the United States on November 4, 2020*

First of all any tool should be judged by its cost vs performance. I'm a professional contractor specializing in bathroom remodeling so marble, ceramic or porcelain tiles are used in every project. Honestly, I didn't expect this hole saw to perform like ones costing considerably more. In fact I've paid at minimum $20.00 each for carbide and as much as two to three times as much for diamond hole saws. My first use with one of these was drilling  through 3/8" porcelain tiles. It cut quickly and continued cutting several holes without diminished performance. I'm sure I could use just one of these on several several projects. Bottom line is they out performed my expectations for such a low cost tool  and I'm totally satisfied!
