Rokrou Diamond Hole Saw Set 15 PCS Tile Hole Saw Kit with Drill Guide from 6mm-50mm /1/4‘’- 2” for Ceramic,Glass,Porcelain,Marble

Im installing a bathroom in my basement, and the shower is 100% tile, clay tile! I needed to install the water flow/temp control valve so I had to cut a 2 hole in the tile. I figured I could use my roto-zip with a tile/ceramic bit. I was wrong! I burned up 3 bits and only got about 70% of the hole cut. I purchased these cutting bits and they work great! I took the 2 bit and it ate through the tile in 15 seconds. Then I had to cut a 3/4 hole for the shower head, and it zipped through like a champ! I cant speak for longevity, but initial efficacy is outstanding! 10/10 would recommend.

I bought this to drill through some marble and porcelain tile for a shower glass panel install. The guide helped in making clean holes and it held well. One of the bits completely bent out of shape on the first hole through the marble. I was still able to finish my install with another bit, with no further issues.

The bits are well made and withstood the task at hand which was about 1.5 of solid granite. The odd contraption they include with the bits is honestly a terrible attempt at whatever it is they thought they were solving. It is useless. I just chucked it away. I use a 90 degree portable press to prime my hole and then finish it off by hand with the drill. I wish theyd shave off the price and save us the extra plastic and bearings. Other than that, a great product.

Was skeptical at first because of the low price. Used it to bore holes in quartz counter top. Was a bit wobbly to start. Without rushing, it handles the job well.

Cut through glass exactly as needed. Good tool for the price

Overall, it worked as I needed it too. Out of the box I wasnt enthusiastic. The product came with a screw driver that extremely rusty. The products screws werent put in well so I thought I broke the product the moment I used it.

great value for simple projects - not professional grade. perfect for homeowner - USE A SPONGE TO KEEP WET, SLOW AND EASY ON PORCELAIN. 10 holes in porcelain w one bit so far. slow and easy take your time its not wood.

Bits have lasted many holes Guide is helpful

In holding on tiles is a little problem.
