Norton 78072721230 Abrasive Belt 100 Grit 2x48 in

Product Description

The NORTON 78072721230 is a coated abrasive belt designed for dry grinding, blending, and finishing applications on metal, wood, and composite surfaces. Built on an X-weight cloth backing with a closed-coat aluminum oxide grain pattern, it delivers consistent cut rates and surface finish across the belt's full life. At 2 inches wide and 48 inches in overall length, it fits a wide range of stationary and portable belt grinders and sanders commonly used by metalworkers, pipefitters, welders, and fabricators. The 100 grit medium grade makes it well suited for general stock removal, weld blending, and intermediate finishing passes.

This belt is part of the Norton R228 series, engineered for dry-only operation on both bench-top belt grinders and handheld belt sanding tools. It is a practical choice for trade and industrial environments where consistent surface conditioning is required before coating, inspection, or fitment. The closed-coat construction keeps abrasive grain density high across the belt face, reducing skip marks and maintaining uniform finish quality throughout the cut cycle.

Key Features

• 100 grit medium grade aluminum oxide grain for general stock removal and weld blending

Compatibility

Designed as a standard replacement coated abrasive belt for 2 inches by 48 inches belt grinders and portable belt sanding machines that accept open-seam or butt-joint belts of this dimension.

Installation Notes

Installation is performed by grinding equipment operators and maintenance personnel. Power down and lockout the belt grinder before changing the belt. Verify belt tracking alignment after installation and run the machine briefly at low tension before full-speed operation.
