Norton 78072728789 Abrasive Belt 120 Grit 3x132 in

Product Description

The NORTON 78072728789 is a coated abrasive belt designed for aggressive stock removal and finishing on metal and other hard surfaces. Built on a heavy-duty X-weight polyester cloth backing, this belt handles the tension and flex demands of wide belt and stationary belt grinder applications. The zirconia alumina abrasive grain runs at 120 grit, a medium grade suited for blending welds, deburring, and intermediate surface finishing. Closed coat density means more abrasive grain per square inch, delivering consistent cut rates and uniform scratch patterns throughout the belt's service life.

This belt measures 3 inches wide by 132 inches long, making it a fit for floor-standing and pedestal belt grinders common in fabrication shops, maintenance facilities, and industrial finishing operations. It is rated for both wet and dry operation, giving technicians flexibility in their grinding setup. The Series R823P designation identifies it as a production-grade belt intended for continuous-duty grinding environments. Metal fabricators, maintenance machinists, and industrial service technicians are the primary users of this belt configuration.
