Norton 662611-40502 Sanding Disc 5 Inch A975 P80B Grit

Product Description

The NORTON 662611-40502 is a pressure-sensitive adhesive sanding disc designed for surface preparation, material removal, and finishing applications. At 5 inches in diameter with no center hole, this disc mounts directly to PSA-style backup pads for use with random orbital and disc sanders. The A975 film backing provides consistent cut and durability across extended runs. The P80B grit designation places this disc in the coarse range, suited for aggressive stock removal, leveling, and preparation prior to finer finishing stages. It is sold individually and available in bulk quantities starting at 100 units per order.

These discs are used in automotive bodywork, metal fabrication, woodworking shops, and industrial surface prep environments. The no-hole format suits operations where dust extraction through the disc is not required or where solid backup pads are in use. The P80B coarse grit is effective for initial material removal on bare metal, wood, composites, and painted surfaces prior to refinishing. Technicians and production workers handling repetitive grinding and blending tasks will find the film-backed A975 construction maintains cut rate through longer service intervals than standard paper-backed alternatives.

Key Features

• 5-inch diameter, no-hole disc format for use with PSA backup pads
• A975 film backing for extended durability and consistent cut rate
• P80B coarse grit for aggressive stock removal and surface leveling
• Pressure-sensitive adhesive mount for quick disc changes
• Bulk ordering available, minimum quantity of 100 units

Compatibility

Designed for use with 5-inch PSA-style backup pads on random orbital sanders and disc sanders that accept no-hole, adhesive-backed abrasive discs.

Installation Notes

Mounting is performed by peeling the liner from the adhesive backing and pressing firmly onto a clean, dry PSA backup pad. Ensure the backup pad surface is free of debris or residual adhesive before applying a new disc to maintain a secure bond. Follow equipment manufacturer guidelines for maximum operating speed, and wear appropriate eye and respiratory protection during sanding operations. Discs should be discarded when cut rate diminishes or when the abrasive surface shows uneven wear.
