Norton 66261136684 Psa Disc 16 in 50 Grit Aluminum Oxide

Product Description

The NORTON 66261136684 is a pressure-sensitive adhesive (PSA) abrasive disc designed for aggressive material removal on flat and curved surfaces. The disc measures 16 inches in diameter and features 50-grit aluminum oxide abrasive, placing it firmly in the coarse grade range. An X-weight cloth backing provides the flexibility and durability needed to handle high-pressure grinding and blending tasks without tearing or delaminating. This disc is a direct peel-and-stick replacement for standard PSA backing plate setups used in floor sanding, metal fabrication, and industrial finishing applications.

This disc is suited for use on metal, wood, composites, and similar hard surfaces where rapid stock removal is the primary objective. The coarse 50-grit cut is appropriate for initial material removal, weld blending, or surface prep before stepping down to finer grits. The flexible cloth construction allows it to conform slightly to irregular surfaces. It is commonly installed by metalworkers, floor finishing crews, and industrial maintenance technicians using large-format disc sanders or grinder setups with PSA backing plates.

Key Features

• 16-inch diameter fits large-format PSA backing plate sanders and floor machines
• 50-grit aluminum oxide abrasive delivers fast, coarse stock removal
• X-weight cloth backing resists tearing under high-load applications
• Flexible construction allows the disc to conform to slightly uneven surfaces
• Pressure-sensitive adhesive mount — no fasteners or clamps required
• No vacuum holes, suitable for use without dust extraction ports

Compatibility

Designed as an OEM-style replacement PSA abrasive disc for large-format sanders and grinders equipped with 16-inch PSA backing plates.

Installation Notes

Installation is performed by trades and technicians using large-format disc grinding or sanding equipment. Before mounting, ensure the PSA backing plate is clean and free of adhesive residue from the previous disc. Peel the liner, align the disc to the backing plate, and apply firm even pressure from the center outward to eliminate air pockets. Power down and lock out the machine before disc changes in accordance with applicable OSHA lockout/tagout procedures.
