Built on a heavy Y-weight cloth backing, this belt runs on standard belt grinders and portable belt sanders. It carries a 36-grit, very coarse grade of zirconia alumina abrasive in a closed-coat configuration, which delivers consistent cut rates on steel, stainless, aluminum, and other hard metals. At 2.5 inches wide and 48 inches long, it fits a common class of stationary and handheld grinding equipment used in shops and on job sites. Dry operation is specified. The belt belongs to the R821P series from NORTON.\u003c\/p\u003e\n\u003cp\u003eThis belt is suited for weld seam blending, heavy stock removal, and deburring on metal workpieces. The zirconia alumina grain self-sharpens under pressure, making it productive on hard ferrous and non-ferrous metals where aluminum oxide belts dull quickly. The closed-coat density maximizes grain coverage for faster cutting action. Typical users include fabricators, pipefitters, ironworkers, and maintenance mechanics who require consistent performance across long runs at elevated pressure and heat.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e36 grit, very coarse grade for maximum stock removal\u003c\/li\u003e\n  \u003cli\u003eZirconia alumina abrasive self-sharpens under pressure for extended belt life\u003c\/li\u003e\n  \u003cli\u003eClosed-coat construction maximizes grain density and cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eHeavy Y-weight cloth backing resists tearing under high-pressure grinding\u003c\/li\u003e\n  \u003cli\u003eDry operation rated — not intended for wet grinding use\u003c\/li\u003e\n  \u003cli\u003eR821P series construction for consistent splice strength and tracking stability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement belt for belt grinders and stationary or portable belt sanders accepting a 2.5-inch by 48-inch abrasive belt in dry-operation configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eBelt installation should be performed by a qualified operator following the equipment manufacturer's tracking and tensioning procedures.
