Norton 662611-31497 Sanding Disc 5 Inch A275 P100B Grit

Product Description

The NORTON 662611-31497 is a pressure-sensitive adhesive (PSA) sanding disc designed for professional surface preparation and finishing work. Part of the A275 line, this disc measures 5 inches in diameter and features a P100B grit rating, placing it in the medium-fine range suited for stock removal and surface blending. The disc uses a vacuum-compatible 5-hole pattern to support dust extraction during use. Sold in bulk rolls, these discs are intended for use by auto body technicians, woodworking professionals, painters, and finishing contractors who require consistent, repeatable abrasive performance across high-volume jobs.

These sanding discs are used in residential and commercial finishing applications where a flat, random orbital, or disc sander is paired with a vacuum or dust collection system. The A275 backing and P100B grit combination makes them well suited for bare wood preparation, primer leveling, and light material removal on painted or filled surfaces. The bulk roll format supports high-volume shop environments where disc changes are frequent and per-unit cost control matters.

Key Features

• 5 inch diameter PSA disc with vacuum-ready hole pattern for dust collection compatibility
• A275 series abrasive construction for consistent cut rate and finish quality
• P100B grit rating — medium-fine range suitable for surface blending and primer work
• Pressure-sensitive adhesive backing for quick, secure attachment to PSA backup pads

Compatibility

Designed as an OEM-style replacement abrasive disc for use with 5 inch PSA backup pads on standard random orbital and disc sanders equipped with dust collection ports.

Installation Notes

Installation is performed by surface prep and finishing technicians using compatible PSA backup pads. Ensure the backup pad surface is clean and free of debris before applying each disc to maintain full adhesive contact. Disconnect the sander from power before changing discs. Follow applicable shop safety guidelines for dust collection and respiratory protection when sanding.
