3M™ Cloth Roll, 464W, grade 320, 8 in x 150 ft (203.2 mm x 45.72 m)

The 3M™ Cloth Roll 464W is an abrasive sanding cloth used to create discs and belts for use on stainless steel. It is made with a tough, Y-weight cloth backing and features closed coat construction for consistent sanding action. This silicon carbide abrasive with embedded cork particles and a water-resistant backing make this roll an ideal product for wet applications such as finishing and polishing.The 3M Cloth Roll 464W is best suited for metal sanding and finishing thanks to its durability and fast-cutting abrasive material. Its heavy, Y-weight cloth backing provides smooth operation and durability and can conform to the shape of contoured parts for consistent finishing. The abrasive side features closed coat construction for consistent finishes for an even visual grain pattern. The cork particles embedded in the product help to provide soft, bright finishes for the best polished look. The distinct blue color and cork particle surface help to easily differentiate it from other grits and grains. This cloth uses silicon carbide, which is a popular choice among industry professionals because of its fast cut-rate and smooth finish. This synthetic mineral is very hard and fractures easily, resulting in freshly exposed sharp edges that cut extra fast and produce a smooth, professional-looking finish. Silicon carbide products are commonly used for low-pressure applications such as cleaning and finishing on wood and metal. While it wears faster than aluminum oxide, it produces a superior finish. This cloth also uses a resin bond which is 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 and provides a consistent, fine finish. The waterproof backing also enables the user to rinse areas of the workpiece and the cloth during use to prevent dust and debris from clogging the points of the abrasive, while producing a faster cut at the same time.
