Magnate P37X103S12 37" x 103" Sanding Belt, F Weight, Open Coat - 120 Grit; 3 Belts/Pkg

This belt comes with aluminum oxide, "F" weight, open 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. Open Coat Abrasive Grain Coverage - Abrasive grains cover approximately 50% - 60% of the coated surface. Coat products generally offer greater flexibility, faster cutting, coarser finish and provide a greater resistance to loading. Open Coat products are used widely for woodworking applications, with limited applications for metal.
