4.5'' Aluminum Oxide Resin Fiber Sanding & Grinding Disc

Grinding disc is an abrasive cutting tool designed for material removal, surface smoothing, and edge shaping on hard materials like metal, stone, or concrete. Typically made from bonded abrasive grains (aluminum oxide, silicon carbide, or zirconia) reinforced with fiberglass mesh, these discs attach to angle grinders or bench grinders for high-speed grinding operations.
