Norton 78072728690 Abrasive Belt 80 Grit 2-1/2x60 in

Product Description

The NORTON 78072728690 is a coated abrasive belt designed for aggressive stock removal on metal, wood, and composite surfaces. Running 2-1/2 inches wide and 60 inches long, it fits standard belt grinders and finishing machines sized for that configuration. The abrasive grain is zirconia alumina, a self-sharpening material well suited to high-pressure applications where heat buildup and grain dulling are common failure points. At 80 grit, this belt sits in the coarse range, making it the right choice for weld blending, surface conditioning, and rapid material removal before progressing to finer grits. The closed-coat configuration maximizes grain coverage for consistent cut rate across the belt face.

This belt is rated for both wet and dry operation, giving technicians flexibility depending on the workpiece material and shop setup. The polyester cloth backing provides dimensional stability under tension and resists tearing during aggressive passes. It is a Series R823P belt, appropriate for use on ferrous metals, stainless steel, and other hard materials where zirconia alumina performs best. Fabrication shops, maintenance welders, metal finishers, and industrial grinding operations are the primary users of this belt configuration.

Key Features

• Zirconia alumina grain self-sharpens under pressure for sustained cut rate
• 80 grit coarse grade for rapid stock removal and weld blending
• Closed-coat construction maximizes abrasive coverage across the belt surface
• Polyester cloth backing resists tearing and maintains dimensional stability under load
• Rated for wet and dry operation

Compatibility

Designed as a direct-fit replacement for standard 2-1/2 x 60 inch belt grinder and finishing machine configurations that accept coated abrasive belts of this size.

Installation Notes

Belt grinder and finishing machine installation should be performed by qualified personnel familiar with abrasive tooling. Power down and lock out the machine before changing belts. Verify belt tracking and tension per the machine manufacturer's guidelines before resuming operation. Inspect the belt for tears or delamination prior to each use and replace immediately if damage is found.
