Norton 78072766418 Abrasive Belt 80 Grit 4x48 in

Product Description

The NORTON 78072766418 is a coated abrasive belt designed for dry stock removal and surface finishing on metal, wood, and composite materials. Running on stationary or portable belt sanders, this belt measures 4 inches wide by 48 inches long and is built around an aluminum oxide abrasive bonded to a heavy-duty cloth backing with closed-coat density. At 80 grit, it falls in the medium grade range, making it well suited for aggressive material removal and intermediate blending work. It is a standard choice for fabrication shops, maintenance technicians, and woodworking professionals.

This belt fits belt sander configurations that accept a 4 x 48 inch belt, common in floor-standing and bench-mounted units used across light manufacturing, metal fabrication, and finish carpentry. The R228 series designation indicates this is a production-grade coated abrasive intended for consistent, repeatable stock removal in dry grinding and sanding operations. Typical applications include deburring, weld blending, scale removal, and surface prep before finishing or coating.

Key Features

• Aluminum oxide abrasive material for durable, consistent cutting action

Compatibility

Designed as a standard replacement or consumable belt for belt sanders and grinding machines configured for a 4 x 48 inch abrasive belt in dry operation.

Installation Notes

Belt sanders must be powered off and unplugged before changing abrasive belts. Confirm belt tracking alignment and tension before resuming operation to prevent premature belt failure or edge wear. Always verify that the sander is rated for dry operation before use, as this belt is not designed for wet or coolant-assisted grinding. Wear appropriate PPE including eye protection and gloves during belt changes and operation.
