- At 3M we offer a broad selection of belts to fit most any industrial belt sander. Wider belts are used 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 fit onto edge sanders for sanding flat, narrow surfaces such as panel edges; and narrow belts are used with portable belt sanders for sanding or blending wood pieces such as cabinet doors. Belts come with various splices that join the belt ends. A film media splice achieves a secure bond with a joining film that minimizes chatter marks, ensures a smooth running belt, and produces consistent finishing results. A sine wave splice is constructed of interlocking fingers that enable the splice to travel smoothly over contact wheels, reduce hinging, and provide added strength to the joint area. Sine wave splices are typically used for coarser grades and wide belts as well as on belts that are going to be washed.
