Our 3M™ Cubitron™ II Abrasive Belt 947A built with 3M™ Precision-Shaped Grain cuts metal dramatically faster and cooler, and stays sharp longer than conventional ceramic belts. Its X-weight poly-cotton backing is flexible. This belt is optimized for low and medium pressure applications on stainless steel, mild steels, and aluminum. Fast and FlexibleA closed coat and a grinding aid make our 3M™ Cubitron™ II Abrasive Belt 947A an outstanding option for low to medium pressure applications on heat sensitive metals. The nature of the abrasive structure diverts heat to the swarf, keeping both belt and workpiece cooler. It is now available in grades 40+ (made to order), 60+, 80+ and 120+ adding an improved solution for finer finishing applications. Cutting Edge Performance for Low and Medium Pressure SandingA semi flexible 3M™ Cubitron™ II Abrasive Belt 947A sports an X-weight poly-cotton backing that is flexible and provides excellent tensile strength. A great number of small belt sizes which are nimble and maneuverable ensure operators can get in, over and around intricate parts. These belts are good options for low and medium pressure offhand operations. How 3M Precision-Shaped Grain Works3M™ Precision-Shaped Grain is designed to continuously fracture and form sharp points and edges that easily “slice” through metal. It cuts faster, lasts longer and stays cooler unlike conventional ceramic abrasive grain that tends to “plow” through the metal, causing heat to build up in the workpiece and the abrasive.
