uxcell 2PCS 21mm Diamond Coated Hole Saw Drill Bits for Glass Ceramic Tile Marble Rock Porcelain Bottles Pots Brick

I purchased these hole saw bits to use on my shower that I am remodeling and they worked great. The same size hole saw from Lowes was way more expensive so I figured these were worth a try and I am glad I chose them. I had to cut two holes in large format natural stone tile with lots of veins in it which I was very nervous about. I used these bits in conjunction with a jig from Amazon that suctioned to the tile which was a huge help. I cant speak to how these would be for cutting a lot of holes but for someone looking to just cut a few holes, I highly recommend!

I ordered Jul. 6th with delivery scheduled for September. The bits came within one week!!! (Amazon still thinks they were not delivered LOL). I needed to drill 1” hole through cinderblock basement wall to install electrical outlet outside. I thought this will wear both bits given the price. To my pleasant surprise the first bit chewed through 2x2” of Cinderblock’s two cement walls with ease. I did not even attempt to cool the bit with stream of water while cutting in. I’d only dip it in a can of cold water every 30 seconds or so. That was enough. Job done in under 5 minutes, the bit is still looking good and ready for future use, while second bit Remains in unused condition. Great tool for DIY-er at a very, very low price compared to what local hardware store would charge for same diameter diamond coated home saw.

Good value for the $$. Used this to cut a hole in some ceramic tile and it worked great. Reading the other reviews, I used a piece of wood and cut out a hole in the wood to use as a template. Used to wood with the pre-cut hole to hold this hole saw in place while I cut into our ceramic tile (would have been tough to drill in exact location needed w/o using the template). Added a little bit of water to keep this hole saw from over-heating.Results turned out great and was much cheaper then purchasing in the store.

I purchased a 2 pack of these 25mm Diamond Coated Hole Saws for a fraction of the cost of one piece from the home store. I didn't think I needed to spend that kind of money for something I'll use a few times a year. I was very pleased with the performance of the tool. I cut a template hole in a plywood scrap with a regular hole saw, and clamped it gently to the tile and streamed water around the bit while I cut the hole. The bit still looks pristine. Perhaps the users that had issues with the abrasive material coming off the tool used it dry and overheated it?

I used this drill to cut a faucet hole through a 7mm thick ceramic tile. I cut the hole before I mounted the tile. I used a drill press and a rubber mat under the tile, and a small spray bottle of water to keep the drill cool and clear. I only cut one hole so far, but it cut through like a hole saw through soft wood. I anticipate getting several holes from each drill. It was very easy. I would use these whenever I needed to cut holes through tiles.

Happy it came with 2 these things die out as soon as you use them, made it 1/2 way through and already the first was spent and I had to switch, that said I only needed it for this one hole and wasn't about to drop 40 bucks, great value, material I was drilling through was marble and a little plywood which I used to guide it, I also sprayed it with water as it started overheating rather fast

I received 2 of these hole saws together...I used one to drill 3 holes and I was pleased. Just a hint of advice - I used a 1" wood bit and drilled a hole in a small piece of 5/8" wood - I clamped the wood on the tile and used it for a guide and it worked out perfect. I did use a little water while drilling...thanks

I used this to cut a hole in a kiln shelf for my forge. The only thing that was hard was to keep it centered where I needed the hole. I had to clean it up with a carbide Dremel attachment.

It does the job but not heavy duty needed two for the job will recommend buying a set as one on its own is not enough.
