Norton 66261136696 Psa Disc 18 in 60 Grit Aluminum Oxide

Product Description

The NORTON 66261136696 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on large flat surfaces. Built on an X-weight cloth backing, this disc delivers the rigidity and durability needed for demanding grinding and finishing applications. The aluminum oxide abrasive cuts consistently across ferrous and non-ferrous metals, wood composites, and other hard substrates. At 60 grit, it falls in the medium-coarse range, making it well suited for stock removal, weld blending, and surface preparation before finer finishing passes. The flexible cloth construction conforms slightly to contoured workpieces, reducing gouging on irregular surfaces. Licensed trade professionals and industrial fabricators are the primary installers and users of this disc.

This disc is intended for use on 18-inch PSA-compatible rotary finishing machines, back-stand grinders, or large disc sanders commonly found in metal fabrication shops, woodworking facilities, and industrial maintenance operations. The brown X-weight cloth backing holds up under high-pressure, high-heat conditions. No vacuum holes are present, so it is best matched with solid platen or non-perforated backing pad assemblies. The R228 series designation identifies it within the NORTON coated abrasives line.

Key Features

Compatibility

Designed for use with 18-inch PSA-style rotary disc sanders, back-stand grinders, and large disc finishing machines equipped with a solid or non-perforated backing pad.

Installation Notes

Installation is performed by machine operators and abrasive specialists in industrial or fabrication settings. Before mounting, ensure the machine is powered off and the backing pad is clean and free of adhesive residue from the previous disc. Press the PSA disc firmly and evenly onto the backing pad from the center outward to prevent air pockets. Inspect the disc for tears or delamination before powering the machine on.
