Product Details
The 3M™ cloth belt 340D measures 6 inches by 48 inches and features P100 grit aluminum oxide abrasive grains bonded with resin to a durable cotton cloth backing, providing continuous cut and long life. This belt has an open coat and load-resistant coating, making it particularly suitable for sanding soft woods. The washable backing is designed for high production environments where the belt may require periodic washing to remove soft wood resin or pitch buildup. Aluminum oxide mineral is widely used industrially due to its cut rate, durability, and longevity, and can be applied to a wide range of materials in both woodworking and metalworking, including ferrous alloys. The abrasive grains are firmly adhered to the cloth backing with resin to withstand high heat and pressure. Abrasive belts come in various widths and lengths for use with different belt sanding tools and applications, such as wide belts for dimensioning or finishing wood panels and smoothing metal sheet edges, medium-width belts for sanding flat, narrow surfaces like panel edges, and narrow belts for portable sanders used on wood pieces such as cabinet doors. Belt ends are joined with various splices, including film media splices that minimize chatter marks and sine wave splices made of interlocking fingers to reduce hinging and strengthen the joint, typically used for coarser grades. Warranty information is not specified in the provided description.
