Diamond cup brush is a very special type of cup brush. It's suitable for relatively fine grinding. With a soft cutting ability, a diamond wire cup brush can deal with small burrs on the surface of the workpiece, as well as clean the rusts without damaging the workpiece itself. At the same time, compared with the wire type cup brush, diamond cup brush has longer service life because it is not easy for a diamond stainless steel wire cup brush to wear and tear. Of course, the price can be higher. We also provide custom diamond cup brush service. Customers can choose according to their own needs for the brush material and silicon carbide, alumina, and other abrasive wire to achieve the effects they want. But we suggest the use of the corresponding mesh abrasive wire.
