Norton 78072764448 Abrasive Belt 320 Grit 2-1/2x60 in

Product Description

The NORTON 78072764448 is a coated abrasive belt designed for dry precision finishing and surface preparation on a wide range of workpieces. Built on a heavy-duty X-weight cloth backing with a closed-coat aluminum oxide abrasive layer, this belt delivers consistent cut and finish at 320 grit extra fine. Measuring 2.5 inches wide and 60 inches long, it fits standard stationary and portable belt sanders used in metal fabrication, woodworking, and general industrial applications. Aluminum oxide abrasive is a durable, self-fracturing mineral well-suited to ferrous metals, hardwoods, and composites. The closed-coat construction maximizes abrasive coverage for smooth, uniform finishes on final-pass and light stock removal work.

This belt is intended for dry operation and is a practical choice for finishing passes on flat and contoured surfaces in shop and field environments. Typical applications include weld blending, paint prep, wood finish sanding, and deburring. The 60-inch length and 2.5-inch width suit a broad range of common belt sander platforms used in fabrication shops, millwork operations, and maintenance facilities. The extra fine 320 grit makes it most effective at the later stages of a sanding sequence, refining surfaces left by coarser grits.

Key Features

• 320 grit extra fine aluminum oxide abrasive for smooth, controlled final-pass finishing
• Closed-coat construction provides maximum abrasive surface coverage for consistent scratch pattern
• X-weight cloth backing delivers flexibility and strength under continuous belt sander load
• Dry operation only — suitable for metal, wood, and composite surfaces
• Series R228 construction for reliable splice integrity and tracking stability
• Single-unit packaging with no minimum bulk requirement beyond one belt

Compatibility

Designed as an OEM-style replacement or standard consumable for belt sanders accepting 2.5-inch by 60-inch abrasive belts in dry operation.

Installation Notes

Installation of abrasive belts should be performed by qualified shop personnel or maintenance technicians with the sander powered down and unplugged before changing belts. Confirm belt tracking direction against the arrow printed on the inner surface of the belt before mounting. Inspect the platen, contact wheel, and idler for wear or damage prior to fitting a new belt. Follow the tool manufacturer guidelines for belt tension to avoid premature splice failure.
