Review on OCR Concrete Diamond Grinding Grinder by David Barit

Pretty nice tool if you want to level a concrete slab. I used it after removing the tiles to replace the floor in my house. He did an excellent job of making the record smooth and silky. It certainly produces a lot of fine dust, but that's to be expected. I only made about 50 square meters. feet, and it looks like about 25% of the grinding surfaces have been used. So if you do a lot of grinding, this probably isn't a very durable grinding bowl. Didn't fit my grinder. As others have noted, its size is slightly different than the standard 4/4.5" US grinder, although it does come with a shim to adjust it to size. Being concave, the disk holding the grinding head is pressed against the curved surface of the grinding bowl when useful. This, combined with the difference in size, made my grinder's grinding jar a little wobbly. This wasn't a problem during use, but the mug still stays flat on the ground when squeezed. All in all it did a very good job at half the price of a similar product at a local hardware store.
