SHDIATOOL 4-Inch Diamond Cutting & Grinding Disc for Granite, 5/8-11 Flange

I used this as a "cup wheel" basically to prep the stone after hand cutting and for shaping before using the polishing pads. It helps not wear out your low grit pads so fast and it just grinds the stone better than the most aggressive polishing pads do. After hand cutting use this tool to straighten and flatten the edge or if it's a curve you would use it to tune up the curve and get it to 90 degrees. Or even if you were doing a threshold and you needed to make a big Hollywood bevel. This tool is what you would use. It's not the best I've used but you cannot beat this for the money. I used it on actual granite. It would also work for marble and quartz. For small cuts on marble or granite it would be fine too. But not for big cuts. You would need a real blade. It would cut concrete and brick like butter though.

This is the real deal. I’ve used mine constantly for about a year and it shows no sign of stopping. It works well on everything - hard plastic, metal, stone, and concrete. I have not used it on ceramic or glass. It’s not much on wood. The screw on attachment and flat surface have been helpful. This is a good price too. I paid $100 for a similar blade at a fair and still consider it worth the money for what it does. (Those grinding blades that can break are eye killers if you forget your safety glasses). Update - a year or more later…. Still cuts though the edge is not what it was. It has seen a lot of action! I should have said in the previous post that this blade is not best for cutting aluminum as it melts or smears and fills the cutting grit. The same can be said for materials or wood covered in healthy latex paint. The blade is also not designed for cutting or sanding wood, but knocks off rough edges if you’re in a pinch.

perfect for the job

We used this blade to cut through 2" sandstone for a double kitcken sink install. It did well and still has lots of use left in it.

Great cutting wheel. It's solid and have lasted me several cuts so far with minimal sign of wear. I wish the diamonds on the wheel were smaller for a thinner cut but considering this is a value priced cutting wheel this is acceptable. Highly recommended.

Great price, cuts great,grinds fast,best diamond blade I ever bought

Big knob on one side they vaguely show. Not sure if it is on properly. No additional washers etc. No instructions!

This thing is the tits! It goes through concrete like butter

I'm greatly impressed with this product. It's definitely the best cutting wheel I've used so far. It cuts through granite as easily as if it was a sandstone or something similar. It seems very durable too! Excellent quality!

lo uso para devastar piezas de cemento y concreto con marmolina, funciona perfecto y no se ha desgastado, ya lo he usado como 1 mes y sigue funcionando como nuevo

I've only used it to cut concrete so far, but it's amazing. I needed to make a cut flush with a riser at some concrete steps and it worked brilliantly - cut cleaner and faster than a typical segmented diamond blade in my grinder. I'm going to get the 5".

I've only used this for a few cuts on ceramic tile and it does cut cleanly, smoothly and without the need for water. Having the abrasive on all sides does ensure a smooth cut on all sides. Dust produced wasn't too bad either.

Purchased this 'little darling' as part of a kitchen reno which has me removing an old ceramic tile floor and replacing it with new ceramic. Since we are not removing the kitchen cabinets I needed something to give me a decent straight-line cut in the old ceramic tiles just behind the toe-plate of the base cupboards. At first I was a little skeptical about this little gem but after reading the reviews I decided to give it a try. Just finished cutting through approximately 10ft of ceramic tile in less than 40-minutes. (The worse part was reaching in with my Mini Grinder!) This cutting wheel went through the tile like a hot knife through butter and the added bonus is that it's not showing any sign of wear afterwards!!! Will need to make some specific angle cuts on some of the new tiles (where ceramic meets hardwood) and I am very confident that this Champ will handle it with ease. Awesome addition to my toolbox! Update: Forgot to update my review and still raving about this 'little gem'! Completed the kitchen ceramic floor tile and porcelain backsplash. Happy to report that the diamond disk completed all the angle cuts in my 12 x 24 floor tiles, as well as any required notches and narrowing of tile width. Handled all notching and trimming of porcelain backsplash, Arabesque style, tile and still going strong. Pretty confident it will handle my next tiling project with ease. Great investment, more than happy.
