Light Sanding ClothOur 3M™ Cloth Belt 907E is best suited for metal grinding and finishing thanks to its durability and fast cutting abrasive material. Its light, JE-weight rayon cloth backing provides smooth operation and flexibility and can conform to the shape of contoured parts for consistent finishing. The abrasive side features a closed coat for aggressive finishing and a distinct red color helps to easily differentiate it from other types of abrasive minerals.Mixed Ceramic AbrasiveCloth Belt 907E is engineered using 3M™ ceramic grain, which enhances toughness and hardness of the mineral. Ceramic blend products feature aluminum oxide blended with ceramic grain for a harder, longer-lasting abrasive. Perfect for stock removal, ceramic abrasives are engineered to fracture frequently for a super-fast cut and can handle heat and stress applications. Ceramic/aluminum oxide blend surpasses aluminum oxide abrasives in cut-rate and durability and makes this cloth an excellent choice for refining, dimensioning, stock removal, scale removal, stroke sanding and small weld leveling.Heat Resistant and Fast CuttingThis cloth also uses a resin bonding which is specially designed to resist thermal and chemical deterioration, which can occur during sanding. This bond is very tough and excellent for precision work on all types of metals This also allows for faster sanding and a higher cut rate. To further protect heat sensitive alloys from stress cracks and discoloration, we incorporated a grinding aid to help reduce running temperatures. Closed coat construction features a dense spread of abrasive grains across the surface of the cloth. This design cuts fast, is ideal for deburring or producing a grain pattern and provides a consistent, fine finish.
