Magnate E18X48S22 18" x 48" Sanding Belt, F Weight, Closed Coat - 220 Grit; 4 Belts/Pkg

This belt comes with aluminum oxide, "F" weight, closed coat resin paper backing. It has antistatic treatment which helps eliminate or minimize sanding dust build up in the machine. Aluminum Oxide Abrasive Grain - Aluminum oxide is extremely tough and has a wedge shape for high penetration of tough materials without excessive shedding or fracturing of the grain. Aluminum oxide is suited particularly well for grinding high tensile strength materials i.e. carbon steels, alloy steels, tough bronze and hard woods. Aluminum oxide is used whenever toughness ( the ability to resist fracturing ) is the main consideration. Aluminum oxide products are typically brown in color. Closed Coat Abrasive Grain Coverage - Abrasive grains cover 100% of the coated surface. The greater number of abrasive grains normally results in a better finish and a higher amount of stock removal during the useful life of the product. If loading is not a problem, a Closed Coat product will give you superior life and lower cost. Closed Coat products are widely used in metalworking and woodworking applications.
