The Mirka Hiolit XO 43 x 86 in. 150 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 150-grit belt is suited to fine finish sanding and producing a smooth, consistent surface ready for coating. It is finished with Mirka’s TS joint, cut in a sine-wave shape to eliminate the hinge effect and prevent chatter marks across the workpiece. 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.
