Flexible and Fast CuttingAbrasives made with 3M™ Cloth Roll 441D are best suited for metal sanding and finishing thanks to its durability and fast-cutting abrasive material. The x-weight, cotton cloth backing provides smooth operation and durability and can conform to the shape of contoured parts for consistent finishing. This cloth 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 and consistent finish. Silicon carbide products are commonly used for low-pressure applications for finishing on wood, steel and stainless steel. While it wears faster than aluminum oxide, it produces a superior finish throughout the life of the mineral.

Heat Resistant and Fast CuttingThis cloth also uses a resin bonding 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 and provides a consistent finish.
