Diamond cups
— a special kind of nozzles for "grinders" and other similar tools. They have the appearance of a concave bowl (hence the name), on the edge of which a set of protrusions made of abrasive material based on artificial diamonds is located around the circumference. The protrusions can be located in one or two rows, and also have a different configuration, the specific application of the nozzle depends on this; detailed information about this can be found in special sources. Also note here that diamond cups are mainly used for grinding concrete — rough, finishing and profiled: the high hardness of the abrasive allows you to effectively deal with this material.
