3M™ Cloth Belt 441D, P40 A-weight, Config

Flexible and Fast Cutting3M™ Cloth Belt 441D is best suited for metal sanding and finishing thanks to its durability and fast-cutting abrasive material. Its x-weight, cotton cloth backing provides smooth operation and durability and can conform to the shape of contoured parts for consistent finishing. This belt uses silicon carbide, which is a popular choice among industrial 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.

Heat Resistant and Fast CuttingThis belt 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, fine finish.
