Norton 78072728551 Abrasive Belt 80 Grit 1/4x24 in Zirconia

Product Description

The NORTON 78072728551 is a coated abrasive belt engineered for demanding material removal and finishing work on narrow-profile grinding applications. Built on an X-weight polyester cloth backing, this belt delivers the rigidity and tear resistance needed for aggressive stock removal. The abrasive grain is 80-grit zirconia alumina applied at closed coat density, which maximizes surface contact and cutting efficiency per pass. At 0.25 inches wide and 24 inches in overall length, it is sized for file-type belt sanders and precision deburring tools used in metalworking, weld blending, and tight-radius finishing. Suitable for both wet and dry operation, it supports coolant-assisted grinding where heat management is a concern. Part of the R823P series, this belt is a standard production choice for fabrication shops and maintenance technicians.

This belt is commonly used on narrow belt file sanders and rotary file machines in metal fabrication, maintenance, and repair environments. The 80-grit medium grade makes it appropriate for initial weld blending, edge deburring, and surface conditioning on ferrous and non-ferrous metals. Wet operation compatibility allows use in applications where workpiece temperature control is necessary, such as grinding hardened alloys or thin-section parts prone to heat distortion. Trades including pipefitters, millwrights, and sheet metal fabricators typically keep this belt size on hand for tight-clearance grinding tasks where wider belts cannot reach.

Key Features

• 80-grit zirconia alumina grain for aggressive medium-grade cutting and long abrasive life
• Closed coat construction maximizes grain density for faster material removal per pass
• X-weight polyester cloth backing resists tearing and flexing under load
• Rated for both wet and dry operation for flexible use in coolant or dry environments
• Compact 0.25 x 24 inch size fits narrow file-type belt sanders and precision deburring tools
• Part of the R823P series for consistent performance across production applications

Compatibility

Designed as an OEM-style replacement abrasive belt for narrow file-type belt sanders and rotary file machines that accept 0.25 inch wide by 24 inch length belts.

Installation Notes

Installation should be performed by a qualified technician following the tool manufacturer guidelines for belt tensioning and tracking adjustment. Ensure the machine is fully powered off and unplugged before changing the belt. Inspect the backing pad and drive rollers for wear before installing a new belt, as damaged contact surfaces accelerate premature belt failure. Always confirm belt direction of travel aligns with the arrow printed on the belt backing, if present, to ensure proper grain orientation.
