This large 180 mm (7 inch) fan design cup wheel is built for high-productivity grinding on large-scale projects. The wheel's wide diameter covers more surface area to reduce job times, while the fan-shaped segments provide essential cooling and clear away debris. This prevents the wheel from glazing and ensures consistent performance on large concrete and refractory surfaces. It features a standard 22.22 mm arbor for compatibility with large angle grinders and surface grinders.
