Product Details
The 3M™ Cloth Belt 340D measures 52" x 75" and features P180 grit aluminum oxide abrasive grains, providing durability for aggressive stock removal while resisting loading, making it suitable for a variety of applications on wood and metal. This open coat premium grade aluminum oxide cloth belt is recommended for wide belt sanding, edge sanding, or portable belt sanding. The fast-cutting aluminum oxide grains are resin-bonded to a durable cotton cloth backing, ensuring continuous cutting and long life; the open coat and load-resistant coating are especially effective for sanding soft woods. The washable backing is designed for high production environments where belts may need washing to remove soft wood resin or pitch buildup. Aluminum oxide mineral is a popular abrasive for industrial use due to its cut-rate, durability, and long life, and it is suitable for woodworking, metalworking, and ferrous alloys. Abrasive particles are adhered to the cloth backing with resin, creating a strong bond that withstands high heat and pressure. These abrasive belts come in various widths and lengths to fit different belt sanding tools and applications; wider belts are used with wide belt sanders for dimensioning or finishing wood panels and smoothing metal sheet edges, medium-width belts fit edge sanders for sanding flat, narrow surfaces like panel edges, and narrow belts are for portable belt sanders that sand or blend wood pieces such as cabinet doors. The belts incorporate various splices to join ends, with a film media splice that creates a secure bond using a joining film that minimizes chatter marks and ensures smooth operation. Warranty terms apply.
