Norton 78072761978 Abrasive Belt 36 Grit 4x48 in Aluminum Oxide

Product Description

The NORTON 78072761978 is a coated abrasive belt designed for aggressive stock removal on metal, wood, and similar workpiece materials. Built on a heavy X-weight cloth backing, this belt delivers the rigidity and durability needed for high-pressure belt grinding and finishing applications. At 36 grit, it falls in the very coarse range, making it well suited for rapid material removal, weld blending, and surface conditioning where speed matters more than a refined finish. The closed-coat construction packs abrasive grain across the full belt face, maximizing cut rate on each pass.

This belt fits stationary belt grinders, portable belt sanders, and combination bench units that accept a 4-inch by 48-inch belt. It is a dry-use belt and should not be used with cutting fluids or coolants. Common applications include weld seam removal, deburring of fabricated steel parts, shaping hardwood, and aggressive surface prep before secondary finishing. Fabricators, metalworkers, woodworkers, and maintenance technicians are the primary users.

Key Features

• 36 grit very coarse grade for fast, aggressive material removal
• Aluminum oxide abrasive material — durable and consistent cutting on ferrous metals and wood
• Closed-coat construction maximizes grain coverage for higher cut rates
• Heavy X-weight cloth backing resists tearing under high belt tension and contact pressure
• Dry-use rated — no coolant or cutting fluid required
• Series R228 construction for consistent performance run to run

Compatibility

Designed as a direct-fit replacement belt for stationary and portable belt grinders and sanders requiring a 4-inch wide by 48-inch long abrasive belt.

Installation Notes

Installation should be performed by a qualified operator with the sander or grinder fully powered off and unplugged before changing belts. Verify belt tracking direction — most belts have an arrow on the backing indicating the required direction of travel. Confirm that the machine's platen or contact wheel is in good condition before mounting a new belt. Always secure guards and safety covers before returning the machine to service.
