Product Details
Fast-cutting aluminum oxide abrasive grains are resin-bonded to a durable cotton cloth backing to provide continuous cut and long life. This belt features an open coat and load-resistant coating, making it particularly favorable for sanding soft woods. The washable backing is suitable for high production environments where the belt may need washing at intervals to remove soft wood resin or pitch buildup. Aluminum oxide mineral is favored by industrial professionals for its cutting efficiency, durability, and longevity. It is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys, and is the most commonly used industrial abrasive. The abrasive particles are adhered to the cloth backing with resin, creating a strong bond that withstands high heat and pressure. Abrasive belts are available in various widths and lengths, accommodating a range of belt sanding tools for different applications on both wood and metal. At 3M, a broad selection of belts is offered to fit most industrial belt sanders. Wider belts are designed for use with wide belt sanders to dimension or finish wood panels, smooth rough-cut edges of metal sheets, or add a grain pattern to stainless steel sheets. Medium-width belts are designed for edge sanders, suitable for sanding flat, narrow surfaces such as panel edges, while narrow belts fit portable belt sanders used for sanding or blending wood pieces, such as cabinet doors. Belts come with various splices that join the belt ends, including a film media splice for a secure bond with a joining film that minimizes chatter marks, ensures a smooth running belt, and produces consistent finishing results, as well as sine wave splices made of interlocking fingers for smooth travel over contact wheels, reduced hinging, and added strength to the joint area, typically used for coarser grades, wide belts, and belts that will be washed.
