Norton 66254416175 Psa Disc 12in 80 Grit Ceramic

Product Description

The NORTON 66254416175 is a 12-inch PSA (pressure-sensitive adhesive) abrasive disc designed for aggressive material removal on flat surface grinding and finishing applications. Built on a Y-weight cloth backing, this disc handles high-pressure grinding without delaminating or breaking down prematurely. The ceramic abrasive grain is self-sharpening, which maintains a consistent cut rate across the life of the disc. At 80 grit, it sits in the medium-to-coarse range, making it well-suited for stock removal, weld leveling, and surface preparation before finer finishing passes. Part of the R980P series, this disc is orange in color and does not include vacuum holes.

This disc is used in industrial, fabrication, and metalworking environments where a rotary or orbital PSA-style platen grinder accepts 12-inch discs. Typical applications include grinding welds, removing mill scale, shaping metal components, and preparing surfaces for coating or inspection. The Y-weight cloth backing provides the rigidity and durability needed for sustained heavy-duty use on hard metals. It is sold individually but requires a minimum order of 25 units per purchase.

Key Features

• Y-weight cloth backing resists tearing and flexing under high grinding pressure
• PSA mounting system provides fast, secure disc changes on compatible platens
• 80 grit for efficient stock removal and weld leveling
• No vacuum holes — suited for solid platen grinders
• Part of the NORTON R980P series

Compatibility

Designed for use with PSA-style rotary or orbital grinders and platen grinders that accept 12-inch pressure-sensitive adhesive abrasive discs.

Installation Notes

Installation is performed by fabricators, machinists, and metalworking professionals. Before mounting, ensure the grinder is powered off and the platen surface is clean and free of adhesive residue from previous discs. Peel the liner from the PSA backing and apply the disc evenly to the platen, pressing firmly from the center outward to eliminate air pockets. Follow the grinder manufacturer's maximum RPM rating and confirm it is compatible with the disc diameter before operating.
