Flap disc with reinforced plastic backing and M14 threaded coupling with ventilation holes. Zirconium and corundum additive abrasive cloth. Double-flap design with flat backing pad. The overlapping lamellae with a large width ensure an increase in lifetime while the combination of zirconium and corundum increases versatility. Does not overheat the machined material. The M14 thread of the backing pad allows direct mounting without the use of a classic clamping ring. Ideal on stainless steels, high-alloy steels but also suitable for cast iron, aluminium and light alloys. Recommended for use with medium and high power angle grinders.
