Norton 78072720880 Abrasive Belt 150 Grit 1x42 in Aluminum Oxide

Product Description

The NORTON 78072720880 is a coated abrasive belt designed for precision dry sanding on metal, wood, and composite surfaces. Built on a heavyweight polyester cloth backing with an X-weight rating, it delivers durability and flexibility under sustained belt-sander loads. The abrasive material is aluminum oxide in a closed-coat configuration at 150 grit, placing it in the fine grade range. This combination resists loading and maintains consistent cut rate across the full belt cycle. It is a standard consumable stocked and replaced by machinists, metal fabricators, woodworkers, and maintenance trades running 1 inches by 42 inches belt sanders.

This belt fits 1 inches by 42 inches belt sanding machines common in metal finishing, weld blending, and woodworking shops. The Series R228 designation identifies it as part of a NORTON product line engineered for general-purpose stock removal and finishing at fine grit levels. Dry operation is required — this belt is not rated for wet sanding applications. The closed-coat construction makes it well suited for harder materials where an open-coat belt would wear prematurely.

Installation Notes

Installation is performed by the machine operator or maintenance technician. Power down and unplug the belt sander before changing the belt. Confirm belt tracking alignment after installation and run the machine briefly at low load to verify the belt seats correctly on the platen and idler. Do not use this belt in wet or coolant-flooded grinding applications.
