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

Bits have lasted many holes Guide is helpful

Used one time and it worked good to start the hole but the suction cup did not hold. But, I got the hole started and the was the main thing. I don’t know how long it will last since it is plastic.Good for the price

In holding on tiles is a little problem.

an absolute bargain… plunged a handful of holes with this kit. used jig to get things started then removed. with a bit of added water and drill in hammer function I’m honestly super impressed with performance…

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

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

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 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.
