Norton 78072769544 Abrasive Belt 120 Grit Zirconia Alumina

Product Description

The NORTON 78072769544 is a coated abrasive belt designed for aggressive material removal and consistent finishing on metal, wood, and composite surfaces. It measures 3.5 inches wide by 15.5 inches long and runs at 120 grit, placing it in the fine grade range for controlled stock removal and surface prep. The belt uses zirconia alumina abrasive grain, which is self-sharpening under pressure and holds up well in sustained grinding applications. A heavy-duty Y-weight polyester cloth backing resists tearing and flexing under load. This belt is part of the R823P series and suits stationary and portable belt sanding equipment used by metal fabricators, machinists, and finishing technicians.

This belt is suited for both wet and dry operation, making it adaptable to shop environments where coolant or water is used to control heat during grinding. Closed coat density provides maximum abrasive coverage across the belt surface, which improves cut rate and produces a more uniform finish. Typical applications include weld blending, deburring, and surface conditioning on ferrous and non-ferrous metals, as well as hardwood and engineered wood products. It fits belt grinders and sanders that accept a 3.5 inch by 15.5 inch belt.
