Norton 662611-31465 Psa Paper Disc 6 in A275 P150 Grit

Product Description

The NORTON 662611-31465 is a 6-inch PSA (pressure-sensitive adhesive) paper abrasive disc designed for surface preparation and finishing work. The A275 series construction pairs a stearated aluminum oxide abrasive with a flexible paper backing, delivering consistent stock removal and a smooth finish. At P150 grit, this disc is well-suited for intermediate sanding stages where operators are blending surfaces, removing scratches from coarser grits, or prepping for primer and topcoat. These discs are sold individually and are a standard consumable item for shops running PSA-style random orbital or disc sanders.

A275 PSA paper discs in P150 grit see regular use in automotive body shops, woodworking operations, metal fabrication, and general manufacturing environments. The pressure-sensitive adhesive backing allows fast disc changes on PSA-compatible backing plates without the need for hook-and-loop fasteners. This format is common in production settings where high disc throughput and quick changeover matter. Installers and operators should confirm their sander backing plate is rated for PSA disc attachment before use.

Key Features

• 6-inch diameter fits standard PSA random orbital and disc sander backing plates
• A275 series aluminum oxide abrasive with stearated coating to reduce loading on soft materials
• P150 grit for intermediate finishing, scratch blending, and pre-primer surface prep
• Pressure-sensitive adhesive backing for tool-free disc attachment and fast changeover
• Paper backing provides flexibility and conformability across flat and slightly contoured surfaces

Compatibility

Designed for use with PSA-compatible 6-inch backing plates on random orbital sanders and disc sanders in automotive, woodworking, and general metal finishing applications.

Installation Notes

Power down and unplug the sander before changing discs. Align the disc squarely to the backing plate and press firmly across the full surface to ensure full adhesive contact before operation. Discs are single-use consumables and should be replaced when abrasive loading or glazing is observed, as continued use reduces cut rate and surface quality.
