Norton 66261131450 Psa Sanding Disc 1000 Grit 5 in

Product Description

The NORTON 66261131450 is a pressure-sensitive adhesive (PSA) sanding disc designed for fine surface finishing on a wide range of substrates. At 1,000 grit with an ultra fine grade aluminum oxide abrasive, this disc delivers consistent stock removal and smooth surface preparation in the final stages of a finishing sequence. The paper backing is B-weight, offering a balance of flexibility and durability suited to contour and flat-surface work. Each disc measures 5 inches in diameter and weighs approximately 0.04 pounds. It is installed by tradespeople, production finishers, and skilled technicians who require repeatable, fine-grit performance.

This PSA disc is well suited for light material removal, between-coat sanding, and pre-finish surface prep on wood, composites, metal, and painted surfaces. The 5-inch diameter fits standard PSA backup pads used on random orbital and disc sanders common in woodworking shops, auto body facilities, and general fabrication environments. No vacuum holes are included, making this disc appropriate for solid backup pad configurations. The flexible paper construction conforms to mild surface contours without tearing under normal sanding pressure.

Compatibility

Designed as a replacement-style PSA sanding disc compatible with 5-inch solid PSA backup pads used on random orbital sanders and disc sanders requiring ultra fine grit abrasives.

Installation Notes

Installation requires no tools — peel the release liner and press the disc firmly onto a clean, dry 5-inch PSA backup pad. Ensure the backup pad surface is free of debris or adhesive residue from prior discs before applying a new disc, as contamination reduces adhesion and shortens disc life. Discard any disc that shows signs of loading, tearing, or delamination. Follow equipment manufacturer guidelines for maximum operating RPM to avoid disc failure during use.
