Diamond cup wheel or diamond cup grinding wheel is one kind of diamond tools for grinding concrete, granite, marble, and other stones. It is mainly used on angle grinders, but also can be used on floor grinders. Generally, there are 2 different technologies used in diamond cup wheels: one is the sintering type, and the other is the high-frequency welding type.
