Norton 78072722375 Abrasive Belt 120 Grit 4x132 in

Product Description

The NORTON 78072722375 is a coated abrasive belt designed for dry grinding, blending, and finishing operations on metal, wood, and composite surfaces. Built on an X-weight cloth backing with a closed-coat aluminum oxide abrasive layer, it delivers consistent stock removal and a uniform finish at 120 grit medium grade. The belt measures 4 inches wide by 132 inches in overall length, making it a standard fit for wide-belt sanders and similar industrial finishing equipment. It is typically installed and used by metal fabricators, woodworkers, and finishing technicians in production and job-shop environments.

This belt is suited for dry surface preparation, deburring, and finishing passes on flat stock, structural shapes, and panel materials. The Series R228 designation identifies the product line within the NORTON coated abrasives catalog. The closed-coat construction keeps abrasive grain density high across the belt face, which supports aggressive material removal and a consistent finish profile on high-contact applications.

Installation Notes

Abrasive belts should be installed by qualified personnel familiar with the sanding machine manufacturer's tensioning and tracking procedures. Confirm the machine is fully de-energized and the drive system is at rest before changing belts. Inspect the belt for tears or delamination prior to installation and never exceed the machine's rated belt speed. Dry-only belts must not be used with water, cutting fluids, or coolant.
