Norton 662611-36369 Psa Disc Roll A/o P320B 3.5in

Product Description

The NORTON 662611-36369 is a PSA (pressure-sensitive adhesive) disc roll designed for hand-sanding and orbital sanding applications in finishing and surface preparation work. Each disc uses aluminum oxide abrasive on a B-weight anti-loading paper backing, which resists clogging and holds up under moderate pressure. The P320B grit rating places this disc in the extra-fine range, making it well suited for final stock removal, seam blending, and prep work before topcoat application. Each roll contains 100 discs and measures 3.5 inches in diameter with no hole. Cases contain 4 rolls, giving shops and field technicians a practical supply quantity for sustained production use.

These PSA disc rolls are used in automotive bodywork, woodworking, metal fabrication, and general surface finishing. The self-adhesive backing mounts directly to compatible PSA backup pads without the need for hook-and-loop interface layers, keeping setup fast. The extra-fine grit makes this product a strong fit for final sanding passes on primer, filler, and bare wood before coating. Tradespeople working in collision repair, cabinet shops, and light metal finishing will find this grit and format a standard part of their workflow.

Key Features

• Aluminum oxide abrasive provides consistent cutting action across wood, metal, and painted surfaces
• B-weight anti-loading paper backing resists clogging and extends disc life
• P320B extra-fine grit for final surface prep and finish sanding
• 3.5-inch diameter with no hole fits standard PSA backup pads
• 100 discs per roll format reduces packaging waste and speeds disc changes
• Case pack of 4 rolls supports high-volume shop and production use

Compatibility

Designed for use with 3.5-inch PSA (pressure-sensitive adhesive) backup pads compatible with standard orbital and random orbital sanders accepting no-hole PSA discs.

Installation Notes

These discs are installed by trade professionals in automotive, woodworking, and metal finishing environments. Ensure the backup pad surface is clean and free of adhesive residue before applying each disc. Disengage the sander from power before mounting or removing discs. Do not exceed the speed rating of the backup pad in use, and replace discs when cutting action diminishes to avoid heat buildup on the workpiece.
