The Mirka Hiolit XO 30 x 75 in. 120 Grit Cloth Wide Sanding Belt is a semi-open, stiff universal abrasive engineered for belt sanding and machine sanding that demands excellent edge wear resistance and long belt life. Built on a flexible X-weight cotton cloth backing with a blue-fired aluminum oxide grain bonded resin over resin, this 120-grit belt is suited to blending, intermediate sanding, and preparing surfaces for finishing. It uses a durable T joint cut straight through the belt and reinforced on the back, set at an angle to resist chatter and prevent marking the material. Each box contains 5 belts. Hiolit XO delivers consistent, high-quality results on demanding materials including hardwood, softwood, MDF, chipboard, veneer, steel, and composites, making it a dependable choice for woodworking, metalworking, automotive, and finishing shops.
