Product Details
The 3M™ Cloth Belt 340D measures 6" x 132" and features 80 grit aluminum oxide abrasive grains that are resin-bonded to a durable cotton cloth backing, providing continuous cutting action and long life. This belt offers an open coat and load-resistant coating, making it especially suitable for sanding soft woods. The washable backing supports high production environments by allowing periodic cleaning to remove softwood resin or pitch buildup. Aluminum oxide mineral is widely used in industrial applications for its cutting rate, durability, and versatility on woodworking and metalworking materials, including ferrous alloys. The abrasive particles are securely bonded to the cloth backing with resin, ensuring resistance to high heat and pressure. The belt is designed to fit various belt sanding tools, with different widths used for diverse applications: wider belts accommodate wide belt sanders for dimensioning or finishing wood panels and smoothing or texturing metal sheets; medium-width belts fit edge sanders for flat, narrow surfaces; and narrow belts are intended for portable belt sanders on wood pieces like cabinet doors. The belt includes splices such as film media splices that provide a secure bond with minimal chatter marks for smooth running and consistent finishes, or sine wave splices composed of interlocking fingers that travel smoothly over contact wheels, reduce hinging, and offer added joint strength, typically used in coarser grades and wider belts. Warranty information is included but not specified in this description.
