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

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.

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.

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

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

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…

Followed the instructions and worked perfect. Installed new soap dispenser to eliminate counter clutter.

The little bracket thing falls apart every time and I only got two uses out of the bits

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.

Update: The seller reached out to me after reading this review and offered a full refund or replacement. :) Original review: No instructions for the guide are included in the box. I stuck the guide to a clean, flat matte finish ceramic tile (not over a grout line), pressed the lever down, and there was enough suction to keep the guide on the wall, but not enough to keep it from wandering once I started drilling through the tile. I ended up making my own jig out of wood and clamping it in place to keep the bit from wandering. I drilled at medium speed using moderate pressure, pausing every ten seconds or so to mist the area with water. The 40mm bit worked fine, and got through the 7mm ceramic tile in a couple of minutes.

It was missing one of the screws for the mounting
