Norton 78072727473 Abrasive Belt 80 Grit 4x36 in

Product Description

The NORTON 78072727473 is a coated abrasive belt designed for aggressive material removal on metal, wood, and composite surfaces. Built on a polyester cloth backing with a closed-coat zirconia alumina abrasive, this 80-grit belt delivers consistent cut rate and long service life under sustained load. The R821P series construction uses a resin bond system suited for high-pressure belt grinding and finishing applications. At 4 inches wide and 36 inches long, it fits standard bench and pedestal belt grinders used throughout fabrication, welding, and metalworking shops.

This belt is intended for dry grinding and stock removal operations in industrial and trade environments. Fabricators, welders, and metalworkers use it on bench grinders, pedestal grinders, and portable belt sanding units. The zirconia alumina grain self-sharpens under pressure, making it effective for ferrous metals, stainless steel, and hard alloys where aluminum oxide belts wear prematurely. The closed-coat construction maximizes grain coverage for fast, aggressive cutting on harder workpiece materials.

Key Features

• Zirconia alumina abrasive grain self-sharpens under grinding pressure for extended belt life
• Closed-coat construction maximizes abrasive coverage for fast stock removal
• Polyester cloth backing resists tearing and flex fatigue during high-pressure grinding
• 80-grit coarse grade suited for initial stock removal and weld blending
• Dry operation only — not rated for wet or coolant-flooded grinding
• R821P series design optimized for ferrous metals, stainless steel, and hard alloys

Compatibility

Designed as a standard 4 x 36-inch replacement belt for bench grinders, pedestal grinders, and portable belt grinding units that accept this belt size.

Installation Notes

Belt grinder installation and belt changes should be performed by qualified personnel familiar with abrasive tooling safety. Disengage and lock out the grinder power before changing belts. Verify belt tracking and tension per the grinder manufacturer's guidelines before resuming operation. Always confirm the machine's rated belt speed does not exceed the belt's maximum operating speed, and wear appropriate PPE including eye protection during use.
