I just finished and I can't believe how good this product worked. I used the larger ventilated disk to cut 12 pieces of marble mosaic tile. The tiles were 1 and 3/4 inches long and 3/8 inches thick. I used one disk and it still has plenty of life left in it. I took each tile off the sheet and clamped it with a woodworking clamp down to a piece of sheetrock I place on my wooden workbench. I used the Dremel on high speed and it cut through easily. About thirty seconds for each piece. Very dusty so wear eye protection and a mask

Run true and smooth. I've just used two so far and both are preforming excellent. Very little sign of ware. Think these will lasts better than one's I've used previously and at a much better price. Time will tell, but happy so far.

I bought these and a dremel in order to make cuts on a backslpash I was installing in my kitchen. I got these items for the same price I would've cost me to rent a wetsaw from home depot. The diamond wheels are good, they lasted for quite a few cuts before I felt the need to change them out. I used these to cut stone and glass for reference to anyone wondering what material I needed it for. Just keep a spray bottle on hand and use painters tape on the cuts and you will be good.

doubted it, but works better than oem dremel diamond bits at a fraction of the price. love the different sizes and they are sturdy. i used these for mosaic herringbone backsplash tiles (a mix of porcelain & marble pieces). I tried all sorts of tools from tile cutters, tile hand cutters, angle grinder with diamond bit, & wet saw. finally i tried Dremel with a diamond bit that costs $30 but it chipped and bent. I saw these on Amazon while looking to replace the Dremel diamond bit, and it was a fraction of the price, with many more sizes and pieces. SOOOOOO glad i got them. If i had found these sooner, i would've saved so much time, effort, and money on wasted mosaic tile sheets!!

I purchased these to help install marble backsplash in my kitchen. These worked great with my dremel. I used 2 disc's for my entire job. This was my only tool for cutting tile!

I was cutting a small stone, .75x 1.5 inches, it through most of it without issue. By the time I tried cutting the other side, the cutting slowed. It started to stain the stone with grey dust that was very hard to get off. I unable to make the second cut with the same blade. I used water to keep it cool and make short contact cuts.Will not buy this item again.

I had to remove a broken pinion shaft and lock bolt inside a differential carrier, and the only way to do it was to dig through the thick hardened steel of the full pinion shaft itself after the broken lock bolt had destroyed multiple titanium, cobalt, and carbide bits. I used these in combination with diamond coated hole saw bits. These rotary cutting wheels made substantial progress and allowed me to dig a substantial divot that permitted the final use of the hole saw bits. Took about 1.5 hours, but I got it all apart, and I only used a couple wheels that showed modest wear. Great solution for the price, should have started with these.

I have not used these wheels as yet but they look to be of good quality. They arrived well packaged with no damage. I will be using these wheels to trim small pieces of opal before polishing.
