💎 6mm 50mm Ceramic Porcelain Rokrou Diamond Review

The set works well. The bits cut well and do their job. Take your time and don't push too hard. Keep water in the channels when cutting. Larger drill bits are a few millimeters shorter so the plug sits on the inside and hits the back and stops drilling. Hit the shank with a hammer and it knocks out the last few millimeters of granite underneath and pierces through it.

Haven't tried it yet. But all the drills were packed in ziplock bags, and the "sandy" texture around the base of the drills left marks in the bag. It's like someone sanded the ends and glued metal dust to the ends to saw through tougher materials. I'll try anyway (hahaha) and out of there. I'm not sure yet if I'll get it back. As pictured, it is basically how it was sent... one box within a box within another box... and one package.

we used 2 inch and 3/4 inch. Both cut perfect holes in porcelain stoneware! After about 4 3/4 cuts it still looks and cuts like new. I was hesitant to save up on these but they work so well. We used our wet saw to let the water through while drilling and the tile came out perfectly. I would definitely order from this brand again. The only problem is that the cage on the teat isn't small enough to hold the smaller ones. I just held them on either side and it worked fine.

Just received this today and was initially disappointed to find the nut on the suction mount was missing. I didn't want to bother with the return so I treated it as is. The hole saw bits worked well and I was able to drill the 10 holes required in less than 2 hours. I have no idea of its durability, but the two bits I used have less diamond coating than when I started, so I'd be surprised if I could drill too many holes in both.
