Norton 662611-31490 Sanding Disc 5 in A275 P320B Grit

Product Description

The NORTON 662611-31490 is a pressure-sensitive adhesive (PSA) sanding disc designed for surface preparation and finishing work. Part of the A275 line, this disc measures 5 inches in diameter and features a 5-hole vacuum pattern for dust extraction during sanding operations. The P320B grit rating places it in the fine finishing range, making it well suited for final passes before coating or topcoat application. These discs come in bulk roll format and are sold individually, with a minimum order quantity of 100 units, making them a practical stock item for shops and field crews with ongoing sanding needs.

This disc is used in automotive body repair, woodworking, and general surface finishing applications. The PSA backing allows fast disc changes on compatible random orbital and orbital sanders equipped with a smooth or hook-and-loop converted platen pad. The 5-hole vacuum pattern aligns with standard 5-inch dust-collection platens to maintain visibility and reduce airborne particulate during work. Typical users include auto body technicians, finish carpenters, and general contractors performing prep work ahead of paint or clear-coat application.

Key Features

• P320B fine grit for finish sanding and pre-coating surface prep
• 5-inch diameter fits standard 5-inch orbital sanding platens
• 5-hole vacuum pattern supports dust extraction at the work surface
• PSA (pressure-sensitive adhesive) backing for quick, secure disc attachment
• A275 series construction for consistent cut rate across the disc face
• Bulk roll format supports high-volume shop use with minimum order of 100 units

Compatibility

Designed for use with 5-inch PSA-compatible random orbital and orbital sanders with a 5-hole dust-extraction platen pattern. Confirm platen type before ordering, as PSA discs require a smooth or foam interface pad rather than a hook-and-loop surface.

Installation Notes

Power down and unplug the sander before changing discs. Peel the disc from the roll and press firmly onto a clean, dry PSA platen pad to ensure full adhesion across the disc face. Avoid applying discs to worn or contaminated pads, as reduced adhesion can cause the disc to detach during operation. Dispose of used discs in accordance with local regulations if sanding coated or treated surfaces.
