Norton 662611-31492 5 Inch P240B Sanding Disc A275 Psa Roll

Product Description

The NORTON 662611-31492 is a PSA (pressure-sensitive adhesive) sanding disc designed for use with random orbital and disc sanders equipped with vacuum extraction. Part of the A275 series, this disc measures 5 inches in diameter with a 5-hole vacuum pattern and carries a P240B grit rating — a fine finishing grit suited for final material removal, surface leveling, and prep work before topcoat application. These discs are sold in bulk rolls, making them a practical choice for high-volume finishing operations where frequent disc changes are routine.

These discs are intended for professional finishing environments including automotive body shops, cabinet shops, flooring contractors, and general woodworking or composite surface work. The A275 designation indicates an aluminum oxide or engineered abrasive construction optimized for consistent cut rate and extended disc life across wood, paint, and light composites. The P240B grit is appropriate for fine sanding stages where scratch minimization and surface uniformity are the primary goals.

Key Features

• 5-inch diameter with 5-hole vacuum port pattern for dust extraction compatibility
• P240B fine grit rating for finish sanding and pre-topcoat surface prep
• PSA backing for fast, tool-free disc changes on compatible sander pads
• A275 series construction for consistent abrasive performance and cut life
• Bulk roll packaging (quantity 6 per package) supports high-volume use

Compatibility

Designed for use with 5-inch PSA-compatible random orbital or disc sanders fitted with 5-hole vacuum extraction pads. Confirm sander pad type accepts PSA-backed discs before ordering.

Installation Notes

PSA discs are installed by peeling the release liner and pressing firmly onto a clean, dry sander pad. Ensure the vacuum holes on the disc align with the holes on the sander pad for proper dust extraction. Discs should be replaced when abrasive loading, glazing, or backing delamination is observed. Handle with clean, dry hands to preserve adhesive integrity before application.
