Norton 662611-31488 5 Inch Psa Sanding Disc A275 P400B

Product Description

The NORTON 662611-31488 is a pressure-sensitive adhesive (PSA) sanding disc in the A275 series, designed for bulk roll application in professional finishing and surface preparation work. Each disc measures 5 inches in diameter with a 5-hole vacuum port pattern to support dust extraction during use. The P400B grit designation places these discs in the ultra-fine finishing range, suited for final sanding passes on wood, automotive body filler, primers, and similar substrates. These discs are sold in roll format and are intended for high-volume, production-level sanding operations where consistent finish quality and efficient stock management are priorities.

These PSA sanding discs are used in woodworking shops, automotive body shops, cabinet finishing facilities, and general surface prep environments. The 5-inch format fits a wide range of 5-hole random orbital and orbital sanders used by finish carpenters, auto body technicians, and production line operators. The vacuum-compatible hole pattern supports connected dust collection, keeping the work surface clean and extending disc life. The roll format is suited for facilities that consume discs at high volume and want to minimize per-unit packaging waste.

Key Features

• P400B ultra-fine grit for final-pass finishing on wood, primer, and body filler
• PSA backing for quick, secure disc mounting to compatible sander pads
• 5-hole vacuum port pattern supports dust extraction and keeps the work surface clear
• 5-inch diameter fits standard random orbital sanders with 5-hole hook-and-loop or PSA backup pads
• A275 series construction for consistent cut rate and finish quality across the roll
• Bulk roll format reduces downtime during high-volume disc changes

Compatibility

Designed for use with 5-inch, 5-hole PSA backup pads on random orbital and orbital sanders commonly used in woodworking, cabinet, and automotive finishing applications.

Installation Notes

PSA discs must be applied to a clean, dry backup pad free of adhesive residue from previous discs. Worn or contaminated backup pads reduce adhesion and can cause disc slippage during use. Ensure the sander is powered off and unplugged before mounting or removing discs. Discard discs that show signs of loading, tearing, or loss of grit to maintain finish consistency and avoid scratch patterns.
