These are great, but I found they wear out fast if you force them through the stone. I have cut several geodes with them and it cut easy and fast. Just don't put too much force.

These babies do the job. I had to cut some glazed ceramic, and it cut through like butter. I did use a little water, but these cutters work like a charm. And it barely seemed to wear down! Great purchase!

These blades along with the Dremel flexible extension worked wonders for cutting tile (glass and ceramic) in tight places with contours and angles. One blade worked for the whole job just don't rush it and let the blade do the work. Great deal!

I bought these to cut down square bottles to make glasses. I have tried many other methods to cut down these square bottles, so far these discs are the only thing that has worked!

Very Pleased with this Company, This Product, and other products of theirs we have bought. I am using these discs to fine-tune porcelain tile notches and using a small dropper to add water to the cut line occasionally.

I needed to grind some cast iron off of an antique bottle opener to make it work easier. The blade did it far more easily than expected. I'm rather amazed at the performance for the price. Now I need to find more things to grind since I have so many disks!

I used these in my Dremel to cut pieces out of china plates. I will add stained glass wings and ahead and make them into angels. The diamond-covered drill bit worked just the way I needed it to and was very durable

These work great, just as good as the ones that originally came with my rotary tool. The cuts are clean and as expected. I am satisfied with these blades and recommend them.

Amazing product. I bought this to cut stacked stone and it was easy. So impressed. I’ve used the same blade to trim mounding too. Considering the purchase cost and quality and performance I’d say this is a great buy.

I'm still using the first blade and it has cut many times more than what a more expensive one I tried before did. And the diamond drill bits are lasting me several times longer than any others including single ones costing almost as much as a 20 pack of these. I believe these are the best diamond products I've used.
