During construction, craftsmen often have to remove various irregularities in the hardened concrete. These can be swells, bumps, protrusions and so on. To make the surface smooth and even, builders use diamond grinding cups. A diamond cup is a disk, on one side of which diamond cutters are applied. Such cutters have increased durability and easily grind concrete. Also such a disk can be used for processing marble or granite. The special feature of this disk is the arrangement of abrasive segments on its surface - this arrangement provides good grinding properties and cooling of the disk.
