KATSU Diamond Grinding Cup Wheel 115mm Angle Grinders Diamond Sanding Disc for Marble Concrete Masonry Granite Stone 99035355

Excellent tool. It made a difficult job of ginding back concrete easy. I would definately recommend the grinding disc. It arrived on time and was good value for money. One thing to note however is that because the grinding disc is so 'dished', its grinding pads stand well forward of the center of the disc so that the key to secure / release it from your angle grinder needs to have fairly long pins. My key couldn't reach the holes in the locking plate so I made a bespoke key with long pins. The performance of the grinding disc made the time spent making the long pinned key worth it.

Seems strong

Used this to rejuvenate chronically stained patio flagstones (concrete/stone mix) - worked really well - upset I wasted many hours trying to do the job with flap-sandpaper wheels and hard-wire wheels - success in mere minutes with this diamond wheel - great value too - - - can't speak too highly of it. Remember you can remove the thin copper bush if necessary to fit your grinder. I also used a rubber washer, about 3 mm thick, to give a more satisfying fit.

This product is highly capable of grinding an uneven surface to a level finish, although you must enclose it with a guard as it throws chips and dust everywhere. This product is capable of grinding hard materials like stone and concrete and softer materials like plaster. All in all a good product.

Good

found out its better than i thought very nice product

To be fair I was expecting it to be pants. But it's awesome. Used to flatted out concrete and brick. Worked a charm

First off, the disc works for grinding concrete and masonry, and it does a reasonable job of this. My main gripe is that the wheel feels unbalanced in use. My Makita grinder wobbles and shakes much more with this compared to other grinding/cutting discs. Also because the wheel is so heavy, it creates a gyroscope effect, which means that it becomes difficult to accurately change angle of the grinder body when the wheel is spinning. It did the one off job I needed it to do, but if I was regularly grinding concrete I would look at better options tbh.

Es muy buen disco ,en hormigón va perfecto pero dónde lo usé y mucho fue en granito ,Rosa porriño para ser exactos ,y mira que es dura esa piedra pues desbasta perfectamente y la durabilidad impresionante, reconozco que este disco es muy pero que muy bueno , le exigi muchísimo , y cumplo a la perfección , de echo me comprare alguno más para tener , por si lo necesito en el futuro para próximos trabajos , porque sé que resuelve perfectamente , no defrauda .100% recomendable
