Norton 78072772454 Abrasive Belt 100 Grit 3.5x15.5 in

Product Description

The NORTON 78072772454 is a coated abrasive belt designed for aggressive material removal and fine finishing on metal, wood, and composite surfaces. Measuring 3.5 inches wide by 15.5 inches long, this belt fits a range of portable and stationary belt sanders commonly used in fabrication shops, metal finishing operations, and woodworking applications. The belt runs on a zirconia alumina abrasive grain at 100 grit, placing it in the fine grade range — suited for surface blending, light stock removal, and pre-finish work. A heavy-duty X-weight polyester cloth backing provides flexibility and tear resistance under sustained pressure.

This belt is part of the R823P series and is engineered for both wet and dry operation, making it appropriate for use where coolant or water is applied to extend belt life or control heat on heat-sensitive workpieces. The closed coat construction maximizes grain coverage across the belt surface, delivering consistent scratch patterns and faster cut rates. It is typically used by metal fabricators, pipefitters, machinists, and maintenance technicians working with ferrous and non-ferrous metals, as well as woodworkers handling hardwoods and engineered materials.

Key Features

• Zirconia alumina grain for durable, self-sharpening cutting action on metal and wood
• 100 grit fine grade for surface blending and pre-finish stock removal
• Closed coat construction for maximum grain density and consistent scratch pattern
• X-weight polyester cloth backing for flexibility and resistance to tearing under load
• Compatible with wet and dry operation for coolant-assisted or dry grinding applications
• R823P series construction for demanding production and maintenance environments

Compatibility

Designed as an OEM-style replacement or stock abrasive belt for belt sanders and grinders accepting a 3.5-inch by 15.5-inch belt configuration in industrial and trade applications.

Installation Notes

Installation should be performed by a qualified operator familiar with belt sander or abrasive grinder equipment. Power down and lockout the machine before mounting or removing the belt. Verify belt tracking and tension according to the equipment manufacturer guidelines before resuming operation. Inspect the belt for tears or fraying prior to each use and replace immediately if damage is found.
