Norton 78072721320 Abrasive Belt 80 Grit 2x72 in Aluminum Oxide

Product Description

The NORTON 78072721320 is a coated abrasive belt designed for aggressive material removal in dry grinding and finishing operations. Measuring 2 inches wide by 72 inches in overall length, it uses aluminum oxide as the abrasive material bonded to an X-weight cloth backing. The closed-coat density ensures maximum abrasive coverage across the belt surface, making it effective for fast stock removal on ferrous metals, wood, and composite materials. At 80 grit, this belt falls in the coarse grade range, suited for shaping, deburring, and rough surface preparation. It is part of the NORTON R228 series and is used by fabricators, metalworkers, woodworkers, and maintenance technicians on standard belt grinders and sanders.

This belt fits stationary and portable belt sander setups that accept a 2 inch by 72 inch belt configuration. It is a practical choice for fabrication shops, weld preparation, and surface conditioning work where dry operation is required. The coarse 80-grit cut is appropriate for initial passes before stepping to finer grit belts. The X-weight cloth backing provides the rigidity and durability needed for high-contact-pressure grinding on belt grinders operating at typical industrial speeds.

Installation Notes

Belt installation should be performed by a qualified operator with the machine fully powered down and locked out per applicable OSHA lockout/tagout procedures. Confirm belt tracking direction arrow aligns with the machine rotation direction before powering on. Inspect the contact wheel and platen for wear or damage before mounting a new belt. Do not exceed the belt speed rating marked on the packaging or the belt grinder manufacturer's maximum SFPM specification.
