The 3M™ PSA Cloth Roll 348D is an abrasive sanding cloth roll constructed on a heavy, x-weight cloth backing that features closed coat construction for finer sanding action. The aluminum oxide abrasive and tough backing make it an ideal product for heavy applications such as aggressive surface sanding and stock removal. Also includes PSA backing for easy attachment and clean removal.The 3M PSA Cloth Roll 348D is best suited for metal sanding and finishing thanks to its durability and fast cutting abrasive material. Its heavy, x-weight cotton cloth backing provides smooth operation and durability and can conform to the shape of contoured parts for consistent finishing. The abrasive side features a closed coat for even finishing. Aluminum oxide is a popular choice among industry professionals because of its fast cut rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional abrasives dull more quickly. Due to its fast cut rate, hardness, and strength, it is widely used for sanding and finishing applications. Aluminum oxide is suitable for use on a wide variety of materials in metal and woodworking. This cloth also uses a resin bond which is specially designed to resist thermal and chemical deterioration, which can occur during sanding. This bond is very tough and excellent for precision work on hard and soft wood. This also allows for faster sanding and a higher cut rate. Closed coat construction features a dense spread of abrasive grains across the surface of the cloth. This design cuts fast, is ideal for deburring or producing a grain pattern and provides a consistent, fine finish.
