Advantages

The benefits at a glance Optimised performance The abrasives used have also been engineered to work with high-speed angle grinders (80 m/s) and are designed to offer a wide range of possible applications. The optimised arrangement of the grinding flaps ensures first-rate grinding performance, long service lives and optimised utilisation to the end. Sustained high performance The cloth flaps are coated with zirconia alumina, ceramic or aluminium oxide and spaced equally on the backing plate. The optimised cloth-reinforced backing guarantees the operator a fresh grit and, thus, consistent removal throughout the entire work process. Extraordinary stability The backing plates included in our SMT range are made of glass fibre or glass-fibre reinforced plastic. They are extremely hard-wearing and deliver optimal power transmission to the work piece. Tried-and-tested safety A special manufacturing process ensures an exceptionally strong bond between baking plate and grinding flaps and produces a level of break resistance that easily exceeds the provisions of the oSa and EN 13743 standards.
