The paper backing provides smooth operation and durability. The abrasive side features a semi-closed coat structure that provides greater grain density to achieve finer finishes than open coat belts. This belt also features our dust management technology that reduces static charge in the dust particles, allowing them to be pulled away when coupled with an efficient dust collection system. To help provide your desired finishing results, the belt ends are joined using a sine wave splice that promotes belt strength and resists hinging and splice fatigue. The splice travels smoothly over contact wheels and platens, minimizes chatter marks, and promotes smooth operation in either direction for consistent finishing results.Our 3M™ Paper Belt 466UZ uses silicon carbide, a synthetic mineral that is very sharp and commonly used for low pressure applications such as final finishing in whitewood sanding. While it breaks down faster than aluminum oxide, it produces a superior finish.Abrasive belts come in many different widths and lengths and are used on a variety of different belt sanding tools for many different applications on both wood and metal. At 3M we offer a broad selection of belts to fit most any industrial belt sander. Wider belts are used to dimension and sand large wooden panels, smooth rough cut edges of metal sheets, or add a grain pattern to stainless steel sheets. Medium-width belts fit onto edge or portable belt sanders for sanding or blending wood pieces such as cabinet doors.
