Product Details
The 3M™ cloth belt 302D measures 1-1/2" x 42" and features a P320 grit aluminum oxide abrasive with an open coat construction that channels sanding dust away from the belt and workpiece for improved visibility and performance. The abrasive and cloth backing are resin bonded to ensure durability and extended use until the abrasive is completely worn. This belt offers added flexibility and is suitable for operations requiring such properties. Aluminum oxide is a widely used industrial abrasive known for its cut rate, durability, and long life, making it effective for both woodworking and metalworking on a wide variety of materials including ferrous alloys. The abrasive particles are adhered to the cloth backing with resin, providing a strong bond that resists high heat and pressure. The open coat design spaces abrasive grains apart, reducing loading caused by wood or paint dust clogging the surface and enabling a more aggressive cut compared to closed coat abrasives of the same grade. The belt is compatible with various belt sanding tools, available in multiple widths and lengths to fit industrial belt sanders. Wider belts are used on wide belt sanders for flat finishing and smoothing metal sheet edges or adding grain patterns to stainless steel sheets. Medium-width belts are used on backstands for weld removal or feed-thru flat finishers for sheet or coil finishing. Narrow belts are suitable for backstands for grinding and finishing or on file tools for finishing in right-angle corners. Typical applications include blending, deburring, fine finishing, and radiusing in metalworking. Warranty terms and specific certifications or compliance details are not provided in the description.
