Abrasive belts are helpful for sanding, grinding, deburring,
blending, and finishing metal, wood and other materials. These
belts are used with belt sanders and grinders to shape a
workpiece, clean surfaces, or provide a fine finish. Belts are
constructed as either coated… Learn More When selecting abrasive
belts, there are several things to consider. The first is grit
size, or grit number, which indicates the size of the abrasive
grain particles adhering to the belt's backing. With a lower
grit size like 40, there are fewer and larger grains in a given
area, making it "coarse" and commonly chosen for removing excess
material and shaping a workpiece. With a high grit size like
400, there are more and smaller grains in a given area, making
it "fine" and creating a smooth surface finish. Also consider
grit material. Aluminum oxide is the most common abrasive
material, chosen because it is durable and compatible with many
different materials. Zirconia alumina is chosen for its fast cut
rate and self-sharpening a
