Sanding disks are circular abrasive discs that remove material, light defects, corrosion, paint, and rust from wood, metal, and plastic surfaces. They attach to disk sanders, angle grinders, or handheld rotary tools, and they allow for good control of a workpiece, as workers can see the workpiece at all times when sanding discs are in use. Coarse grit removes material such as welds on metal or mill marks on wood, while fine grit buffs out tool marks and evens out edges. Adhesive-backed and hook-and-loop discs allow for quick switchouts of sanding disks. Industrial sanding disk rolls keep fresh disks on-hand in applications requiring heavy or frequent sanding, such as in woodshops and production facilities.
