Norton 66261136630 Psa Disc 12 in 40 Grit Aluminum Oxide

Product Description

The NORTON 66261136630 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on flat and contoured surfaces. Built on an X-weight cloth backing, it delivers the rigidity and flex needed for demanding grinding and sanding applications. The disc measures 12 inches in diameter and carries a 40-grit aluminum oxide abrasive, placing it in the coarse grade range — suited for fast stock removal, weld blending, and surface prep before finer finishing passes. It is installed and used by metalworkers, fabricators, and maintenance technicians working with PSA-compatible backing plates and disc sanders.

This disc is appropriate for use on metal, wood, and composite substrates where rapid material removal is the priority. The X-weight cloth backing resists tearing under high pressure and lateral load, making it a reliable choice for industrial grinding operations. The PSA adhesive mount allows quick disc changes without mechanical fasteners. No vacuum holes are included, so it is intended for solid-face backing plates only. The brown disc color is consistent with the Norton R228 series designation.

Installation Notes

Installation is performed by metalworkers, fabricators, or maintenance technicians using PSA-compatible disc sanders or grinders. Power down and disconnect the machine from its power source before removing or applying any abrasive disc. Clean the backing plate surface of debris and residual adhesive before applying the new disc to ensure full contact and proper adhesion. Inspect the disc for damage before use and follow applicable workplace safety guidelines for abrasive equipment operation.
