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

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…

One star off because one of the bearings was off and loose in the box. Thought it was missing a screw, but found it. The diamond saws , is what I expect. Not any better than others I have purchased and not any worse. Use water and they will give you good life. The suction on the guide was weird. It stuck good on tile but did not stick at all to a non porous formica top. Wish there was some sort of case though.

The suction cup doesn’t work on all tile

Bits have lasted many holes Guide is helpful

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.

Was skeptical at first because of the low price. Used it to bore holes in quartz counter top. Was a bit wobbly to start. Without rushing, it handles the job well.

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

Update: Seller contacted me after the following review and offered to replace or refund. Also, after reading other reviews I would like to add a reminder to always use these with water (if you want them to work for more than 1 hole). That goes for any continuous surface diamond cutter. Keep applying water as cutting surface dries. Water will also help flush out the debris. Great selection of sizes for the price. Dont expect to do cut a lot of holes with any one. Found the diamond coating on the inner surface flacked off on the two larger sizes I used. Handy to have the selection of sizes for the occasional use. The slot for debris removal on the smaller sizes is too small. Kept having to stop and try to clean out the debris, which often got stuck inside when drilling porcelain tile. The 1/4 size lasted for about 11 holes going through 3/8 porcelain, thinset, and hardie board (about an inch thick). Should have invested in a good 1/4 diamond holesaw with large debris flute sooner. Way faster.

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.

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.
