Norton 66260306382 Psa Disc 6 in 120 Grit Diamond

Product Description

The NORTON 66260306382 is a 6-inch pressure-sensitive adhesive (PSA) abrasive disc engineered for precision surface finishing applications. Built on a flexible cloth backing, this disc uses diamond abrasive material at 120 grit for consistent, fine-grade stock removal and surface refinement. The PSA mounting system allows quick, tool-free disc changes on compatible backup pads, making it a practical choice for production environments and bench-top grinding setups. Weighing under 0.1 pounds, the disc is lightweight without sacrificing abrasive performance. The black cloth construction resists tearing under load and conforms to contoured workpiece surfaces.

This disc is suited for grinding and finishing hard materials where conventional aluminum oxide or silicon carbide abrasives wear prematurely. Diamond abrasive makes it appropriate for use on carbide tooling, ceramics, glass, stone, composites, and hardened steel. The flexible cloth backing allows the disc to conform slightly to irregular surfaces, which is useful for both flat and lightly contoured workpieces. Machinists, tool-and-die shops, fabrication facilities, and industrial maintenance technicians are the primary installers and users of this disc.

Key Features

Compatibility

Designed for use on PSA-compatible backup pads accepting 6-inch abrasive discs. No specific machine or model compatibility was provided in available product data.

Installation Notes

Installation requires a clean, dry backup pad surface for proper PSA adhesion — residue from previous discs should be removed before mounting. Ensure the backup pad is the correct diameter and rated for the operating speed of the grinder or finishing machine in use. Disc replacement should be performed with the machine powered off and disconnected from its power source. Follow all applicable shop safety guidelines and wear appropriate eye and hand protection when handling abrasive discs.
