This diamond cup wheel, with a diameter of 180 mm, features a double-row design for either fast dry or wet grinding. It is ideal for surface preparation, edge blending, smooth shaping, finishing, and tilt wall finishing of concrete or other masonry surfaces. The lightweight and vibration-free design greatly reduces operator fatigue, while cooling holes allow air to cool down the cup wheel quickly and effectively. Thanks to the 20mm-wide diamond coating, this grinding cup wheel is extra hard and strong, providing a fast cutting rate, high performance, and a long-term service life as well.
