Norton 66261136727 Psa Disc 24 in 80 Grit Aluminum Oxide

Product Description

The NORTON 66261136727 is a pressure-sensitive adhesive (PSA) abrasive disc engineered for heavy-duty surface grinding and stock removal applications. Built on an X-weight cloth backing, this disc delivers the rigidity and durability needed for aggressive material removal on metal, wood, and composite surfaces. The 24-inch diameter makes it well-suited for wide-format sanding machines and large-platen sanders. With 80 grit aluminum oxide abrasive, it cuts fast and holds up under sustained friction and heat. The flexible construction conforms moderately to surface contours without sacrificing cutting action. Fabricators, woodworkers, metal finishers, and industrial maintenance technicians are the primary users of this disc.

This disc is intended for use on large-format PSA-compatible sanding machines found in production woodworking shops, metal fabrication facilities, and industrial finishing operations. The 24-inch size fits wide belt and disc sanding equipment that accepts PSA-mount media. The 80 grit rating makes it appropriate for intermediate stock removal, blending welds, leveling surfaces, and preparing workpieces for finer finishing passes. No vacuum holes are included, so it is best suited for machines that do not rely on dust extraction through the disc face. The R228 series designation indicates this disc is part of a consistent product line designed for repeatable performance in production environments.

Key Features

• 24-inch diameter fits large-format PSA disc sanders and wide-platen machines
• 80 grit aluminum oxide abrasive for fast stock removal and surface blending
• X-weight cloth backing provides strength and resistance to tearing under load
• Pressure-sensitive adhesive mount allows quick disc changes with secure adhesion
• Flexible construction allows moderate contouring to workpiece geometry
• No vacuum holes — suited for solid-platen machines without through-disc dust extraction

Compatibility

Designed as an OEM-style replacement or standard consumable for large-format PSA disc sanding machines that accept 24-inch abrasive discs with adhesive-back mounting.

Installation Notes

Installation is performed by finishing technicians or machine operators familiar with large-format sanding equipment. Before mounting, ensure the sanding platen is clean, dry, and free of adhesive residue from the previous disc to ensure proper bonding. Peel the liner from the PSA backing and apply the disc to the platen with firm, even pressure working from the center outward to eliminate air pockets. Allow the adhesive to seat before resuming machine operation, and follow the equipment manufacturer's maximum RPM rating for the disc diameter in use.
