Norton 66261131463 Psa Disc 5 Inch 100 Grit Aluminum Oxide

Product Description

The NORTON 66261131463 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface preparation, finishing, and material removal on random orbital and disc sanders. Built on a B-weight paper backing, this disc offers a balance of flexibility and durability suited for contoured and flat surfaces. The abrasive material is aluminum oxide at 100 grit, classified as a fine grade, making it well-suited for light stock removal, blending, and pre-finish sanding passes. The disc measures 5 inches in diameter and is sold in packs of 100. No vacuum holes are included, making it appropriate for use on solid backup pads. This is a Series A275 disc intended for professional trades and production finishing environments.

This disc is used in metalworking, woodworking, auto body, and general fabrication applications where consistent fine-grit surface finishing is required. The PSA backing allows for fast disc changes on compatible backup pads without the use of hook-and-loop systems. The flexible paper construction conforms slightly to workpiece geometry, which is useful for contour sanding. Typical users include metal fabricators, body shop technicians, cabinetmakers, and general maintenance trades working on both ferrous and non-ferrous materials.

Installation Notes

Ensure the backup pad surface is clean and free of debris before applying the PSA disc to achieve a secure bond. Power down and unplug the sander before changing discs. Avoid applying the disc to a pad that is still warm from use, as heat can reduce adhesive effectiveness. Discard discs that show signs of loading, tearing, or delamination.
