3M Cloth Disc 481W is an abrasive sanding cloth constructed on a heavy, screen backing that features closed coat construction for aggressive sanding action. The silicon carbide abrasive and flexible backing make this cloth an ideal product for dry applications such as metal surface sanding and stock removal.Screen Sanding Disc
Our 3M Cloth Disc 481W is best suited for metal sanding and finishing thanks to its durability and fast cutting abrasive material. Its heavy, screen 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 aggressive sanding and a distinct black color helps to easily differentiate it from other grits and grains.
Silicon Carbide Abrasive
This abrasive primarily uses silicon carbide, which is a popular choice among industrial professionals because of its fast cut-rate and smooth finish. This 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.
Waterproof and Heat Resistant
This disc also uses a resin bonding that 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 surfaces. This also allows for faster sanding and a higher cut-rate. The waterproof 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.
