Product Details
The 3M™ Cloth Belt 340D measures 36 inches by 75 inches and features P150 grit aluminum oxide. It is an open coat premium grade aluminum oxide cloth belt designed for durability in aggressive stock removal, resistance to loading, and suitability for a variety of applications on wood and metal. Recommended uses include wide belt sanding, edge sanding, and portable belt sanding. The fast-cutting aluminum oxide abrasive grains are resin-bonded to a durable cotton cloth backing, providing continuous cut and long life. Its open coat and load-resistant coating make it particularly effective for sanding soft woods. The washable backing supports high production environments where the belt may require washing to remove resin or pitch buildup. Aluminum oxide mineral is a widely used industrial abrasive known for its cut-rate, durability, and long life across woodworking and metalworking, including ferrous alloys. The abrasive particles are bonded with resin, creating a strong bond that withstands high heat and pressure. These abrasive belts come in various widths and lengths to fit multiple belt sanding tools, from wide belt sanders for dimensioning or finishing wood panels and smoothing metal edges to edge sanders for flat, narrow surfaces and portable belt sanders for sanding or blending wood pieces such as cabinet doors. Belts include various splices, with film media splices providing a secure bond using a joining film to minimize chatter marks and ensure smooth operation. Warranty terms apply as specified by the manufacturer.
