High Quality ConstructionOur 3M™ Cloth Wheel 741A is best suited for metal sanding and finishing thanks to its durability and fast cutting abrasive material. It’s flexible, x-weight 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 of grains for aggressive finishing and a distinct brown maroon helps to easily differentiate it from other cloths.Blended Ceramic Grains3M™ Cloth Wheel 741A is engineered using 3M™ ceramic materials, which enhance the toughness and hardness of the grain. Ceramic blend products feature aluminum oxide blended with ceramic grain for a harder, longer-lasting abrasive. Perfect for stock removal, ceramic abrasives are engineered to fracture frequently for a super-fast cut and can handle intense heat. Ceramic/aluminum oxide blend surpasses aluminum oxide abrasives in cut-rate and durability and makes our 3M™ Cloth Wheel 741A an excellent choice for moderate stock removal and surface preparation. Heat Resistant and Fast CuttingThis wheel 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 wheel. This design cuts fast and is ideal for deburring or producing a grain pattern and provides a consistent, fine finish.
