Scotch-Brite™ SC Surface Conditioning belts work well to remove coarse grindlines, mill marks, or small burrs left by cutting tools or conventional abrasives. 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. Wide belt sanders are used for sanding and finishing large wood panels. Medium-width belts fit onto edge or portable belt sanders for sanding or blending wood pieces such as cabinet doors, and narrow belts are used with file tools in metalworking to access small areas or inside corners. We manufacture Scotch-Brite™ SC Surface Conditioning Belts with a choice of silicon carbide or aluminum oxide abrasive mineral. Silicon carbide is a synthetic mineral that is very sharp and commonly used for low-pressure applications such as paint prep and finishing. Aluminum oxide is a hard, blocky mineral that provides high cut-rate and long life. While silicon carbide breaks down faster than aluminum oxide, it produces a finer finish. Belt sanders are used for rapid grinding, sanding and finishing on a variety of surfaces. Depending on the material being worked, sanding wheels and discs may clog, quickly making them less efficient, while belt sanders continue to sand without clogging because small grooves in the abrasive belt open as they go around the arc of the drive wheel.
