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

Works perfectly. Follow the instructions about low drill speed and plenty of water. Keep it clean and cool and can cut many holes.

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.

Great tool. But hopefully last a little bit longer. Still good choice. Thx

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.

I bought these to cut glass and ceramics. They work as described but won’t last very long. I got two good cuts and the diamond coating was almost completely gone. For big jobs I would purchase their higher quality cutting tools.

The suction cup doesn’t work on all tile

This kit worked well for the application. However, we had to buy a specific bit for our job as a 32mm was not included in the set. It seemed to have virtually everything else. I cannot speak to longevity as weve only used it once after we bought the size bit we needed. The suction cup did slip a little but didnt hurt anything.

Bits work great but the guide not so much!

Overall, the price is good for all these bits and a single project.
