Norton 66261131451 Psa Sanding Disc 5 in 800 Grit 100 Discs

Product Description

The NORTON 66261131451 is a pressure-sensitive adhesive (PSA) sanding disc designed for fine surface finishing and material removal on wood, metal, and composites. Built on a flexible B-weight paper backing, this disc mounts directly to PSA-compatible backup pads without clips or fasteners. The aluminum oxide abrasive grain is rated at 800 grit, placing it in the ultra-fine grade range — suited for final sanding passes, surface prep before finishing, or light stock removal between coats. Each roll contains 100 discs at 5 inches in diameter. The disc carries no vacuum holes, making it appropriate for solid-face backup pads.

This disc is used in metalworking, woodworking, automotive body, and general fabrication applications where a consistent, ultra-fine scratch pattern is required. The flexible B-weight paper backing conforms to slightly contoured surfaces, making it a practical choice for detail work and flat-panel finishing. It is part of the Norton A275 series. Installation requires no tools — discs peel and apply directly to a 5-inch PSA backup pad. This product is sold as a roll of 100 discs and is suited for shop, production, and light industrial environments.

Installation Notes

Installation is performed by trade professionals, fabricators, and skilled operators — no tools are required to mount the disc. Ensure the backup pad surface is clean and free of adhesive residue from previous discs before applying a new one. Power down the sander and disconnect it from its power source before changing discs. Do not exceed the maximum RPM rating of the backup pad in use.
