Sanding belts are abrasive tools used in various power tools, such as belt sanders, to smooth or shape surfaces. They consist of a flexible backing material coated with abrasive particles, which can be made from materials like aluminum oxide or silicon carbide. Sanding belts come in different grits, indicating their coarseness, and are used for tasks ranging from heavy material removal to fine finishing. These belts are commonly used in woodworking, metalworking, and automotive applications. They can be easily replaced on the sander, allowing for quick changes between different grits. Proper selection and maintenance of sanding belts can enhance efficiency and prolong their lifespan.
