Norton 07660749274 Abrasive Belt 120 Grit 4x24 in

Product Description

The NORTON 07660749274 is a coated abrasive belt designed for dry grinding, blending, and finishing applications in metalworking and fabrication environments. Built on a heavy Y-weight cloth backing, this belt delivers the structural rigidity needed for demanding material removal on metal surfaces. The zirconia alumina abrasive grain is self-sharpening and fracture-tough, making it well-suited for aggressive stock removal at 120 grit Fine grade. The open coat density reduces loading and heat buildup, extending belt life across extended use cycles. Licensed tradespeople and fabrication shop technicians are the primary installers and users of this product.

This belt is sized at 4 inches wide by 24 inches long and fits bench-top and portable belt sanders configured for that throat size. It is intended for dry operation only. Typical applications include weld seam blending, surface conditioning, and deburring of steel, stainless steel, and other ferrous metals. The Series R831 designation identifies this as a Norton 3X-series product engineered for consistent cut rate and longer service life compared to standard aluminum oxide belts in comparable grit ranges.

Key Features

• Zirconia alumina grain provides self-sharpening, fracture-tough cutting action for efficient stock removal
• 120 grit Fine grade balances material removal with surface finish quality
• Heavy Y-weight cloth backing resists tearing and flexing under load
• Open coat construction minimizes loading on gummy or soft materials
• Dry operation design — not rated for wet or coolant-flooded use
• Series R831 construction for extended belt life in high-demand fabrication settings

Compatibility

Designed to fit belt sanders and grinders with a 4-inch by 24-inch belt path. Verify sander drive and idler pulley width and belt tracking adjustment range before installation.

Installation Notes

Disconnect and lock out power to the belt sander before changing belts. Inspect the drive and idler pulleys for wear, debris, or misalignment prior to mounting the new belt. Ensure the belt is installed with the arrow on the backing aligned in the direction of sander rotation. Do not use this belt in wet or fluid-cooled applications.
