Norton 78072700400 Abrasive Belt 80 Grit 3x132 in

Product Description

The NORTON 78072700400 is a ceramic-coated abrasive belt engineered for demanding material removal in industrial and trade grinding applications. Running at 80 grit, this medium-grade belt delivers aggressive stock removal on metals, composites, and hard materials. It is built on a Y-weight polyester cloth backing, which provides the rigidity and durability required for heavy-pressure belt grinding. The closed-coat construction keeps abrasive grain density high across the full belt surface, maximizing cut rate and minimizing loading on suitable materials. This belt is rated for both wet and dry operation, giving technicians flexibility depending on the application and coolant requirements.

This belt fits machines with a 3-inch wide platen or contact wheel and requires a 132-inch belt length. It is suited for weld grinding, deburring, and surface conditioning on fabrication shop equipment, including wide-belt grinders and large-format belt finishing machines. The R983 series designation identifies it within Norton's heavy-duty ceramic line, designed for production-level use where belt life and consistent cut rate matter. Typical users include metal fabricators, pipefitters, maintenance machinists, and industrial grinding technicians.

Key Features

• Wet and dry rated for use with or without coolant or cutting fluid
• Part of the R983 series, designed for production and industrial grinding environments

Compatibility

Designed for belt grinding machines accepting a 3-inch wide by 132-inch OAL abrasive belt. Verify platen, contact wheel, and tracking specifications on the host machine before installation.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive belt machinery. Power down and lock out the grinder before changing belts. Confirm belt tracking direction matches the arrow marked on the belt backing before tensioning. Inspect the contact wheel and platen for wear or damage before mounting a new belt, and verify that machine speed rating is compatible with the belt.
