Norton 78072727146 Abrasive Belt 40 Grit 2x72 in Zirconia Alumina

Product Description

The NORTON 78072727146 is a coated abrasive belt designed for aggressive material removal on metal, weld seams, and hard surfaces. It measures 2 inches wide by 72 inches long and runs on standard belt grinders and grinder-polisher machines. The belt uses zirconia alumina abrasive grain at 40 grit, placing it in the extra coarse range for fast stock removal. A closed-coat density ensures maximum grain coverage across the polyester cloth backing, which resists tearing and flexing fatigue during extended runs. This belt is rated for dry use only and is built for the production floor or fabrication shop.

This belt suits metalworking applications including weld blending, deburring, scale removal, and surface conditioning on steel and stainless. It is compatible with belt grinders and file belt machines accepting a 2 by 72 inch belt. Fabricators, pipefitters, and metal finishing techs are the primary users. The Series R821P designation identifies it within the NORTON zirconia alumina coated abrasive line, which is engineered for high-pressure, high-heat grinding conditions where aluminum oxide belts break down prematurely.

Key Features

• 40 grit extra coarse rating for rapid stock removal and weld blending
• Zirconia alumina grain self-sharpens under pressure, extending belt life on ferrous metals
• Closed-coat density maximizes abrasive coverage for consistent cut rate
• Polyester cloth backing resists tearing and maintains dimensional stability under tension
• Dry-use construction suitable for production metalworking environments
• Series R821P engineering targets high-pressure, high-heat grinding applications

Compatibility

Designed to fit belt grinders, grinder-polishers, and file belt machines configured for a 2 by 72 inch abrasive belt. Confirm machine belt size specifications before installation.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians familiar with belt grinder operation. Power down and disconnect the machine from its power source before changing belts. Verify tracking adjustment after installing the new belt and before resuming operation. Always wear appropriate eye and hand protection when operating abrasive belt equipment.
