Sanding discs are circular abrasive discs that remove material, light defects, corrosion, paint, and rust from wood, metal, and plastic surfaces. They attach to disc sanders, angle grinders, or handheld rotary tools, and they allow for good control of a work-piece, as workers can see the work-piece 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 switch-outs of sanding discs. Industrial sanding disc rolls keep fresh discs on-hand in applications requiring heavy or frequent sanding, such as in wood-shops and production facilities.
