Product Details
The 3M™ cloth belt 341D measures 4" x 132" and features 50 grit aluminum oxide abrasive grains resin-bonded to a durable X-weight cotton cloth backing, designed for fast cutting and long-life performance in more aggressive dry sanding applications. It offers a closed coat construction for finishing on metal, providing a consistent fine finish and suitability for producing a grain pattern, with the explicit instruction not to run the belt wet. Aluminum oxide is favored for its cut-rate, durability, and long life and is effective on various materials in woodworking and metalworking, including ferrous alloys. The abrasive particles are secured to the cloth backing with a resin bond that withstands high heat and pressure. The belts are available in various widths and lengths to fit different belt sanding tools, with wider belts used for wide belt sanders on wood panels or metal sheets, medium widths for edge sanders on flat, narrow surfaces, and narrow belts for portable belt sanders on smaller wood pieces. Belt splices include film media splices for secure bonds minimizing chatter marks and sine wave splices made from interlocking fingers that enhance smooth travel over contact wheels, reduce hinging, and strengthen the joint, typically used for coarser grades. Warranty information is included but not specified in this description.
