Norton 66261100988 Psa Disc 12 in 180 Grit Aluminum Oxide

Product Description

The NORTON 66261100988 is a 12-inch PSA (pressure-sensitive adhesive) abrasive disc engineered for flat-surface grinding and finishing applications. Built on a heavy X-weight cloth backing with aluminum oxide abrasive grain at 180 grit, this disc delivers consistent very fine material removal on metal, wood, and composite surfaces. The flexible cloth construction conforms to slight surface irregularities without sacrificing cutting performance. At 0.002 pounds per disc, it is a lightweight consumable suited for high-volume finishing workflows. Installation is tool-free — peel and press onto a compatible 12-inch PSA backup pad.

This disc is used in fabrication shops, woodworking facilities, and metal finishing operations where a 12-inch PSA disc platen or finishing machine is in use. The 180 grit aluminum oxide abrasive is appropriate for final stock removal, surface prep before coating, and blending passes on ferrous and non-ferrous metals as well as hardwoods and engineered wood products. The cloth backing at X weight provides durability under moderate pressure, making it suitable for both hand-assisted and machine-driven applications.

Key Features

Compatibility

Designed for use with 12-inch PSA backup pads and platen-style finishing machines that accept pressure-sensitive adhesive abrasive discs without vacuum holes.

Installation Notes

Installation is performed by the operator running the finishing equipment — no licensed trade certification is required for abrasive disc changes. Ensure the backup pad surface is clean and free of adhesive residue before applying the disc. Power down and de-energize the machine before mounting or removing any abrasive disc. Do not exceed the maximum RPM rating printed on the backup pad or machine spindle.
