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

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

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

Bits have lasted many holes Guide is helpful

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.

Rated 5 star but not 100% satisfied. I should have shopped more as I only needed 1 size to drill travertine shower for anchors. The bit did make 4 holes, where others failed after barely cutting a dimple, but the bit is worn and will not work any further. The suction cup guide did not work at all, as the suction is poor at best. Good bits but kit more than needed and guide plate might work for smooth tile but not travertine.

I installed a new quartz countertop and needed to drill holes for the faucet and vessel sink. This kit made it easy to start the hole and maintain the cut. I only made one hole with two different size bits, so I cant attest to how well they hold up. But the suction apparatus worked great and made the job much easier. Great kit for a home owner.

Suction cups did not work on tile. Bits were great value!

In general work well. But first out of the box failed in 2 minutes. Would have given 5 star because it was inexpensive, had first not failed so fast

It was missing one of the screws for the mounting
