Norton 66260307019 Psa Disc 5 in 200 Grit Diamond

Product Description

The NORTON 66260307019 is a 5-inch PSA (pressure-sensitive adhesive) abrasive disc designed for precision surface finishing and polishing work. Built on a flexible cloth backing, this disc uses diamond abrasive material at a 200-grit very fine grade, making it well-suited for tasks that demand controlled material removal and a refined surface finish. The flexible construction allows the disc to conform to contoured or irregular surfaces without losing abrasive contact. Installers and tradespeople working with hard materials such as stone, tile, concrete, ceramics, or carbide tooling will find this disc appropriate for fine grinding and surface preparation stages.

This disc is intended for use on 5-inch random orbital or right-angle sanders and grinders equipped with a PSA backing pad. The 200-grit very fine diamond abrasive makes it a finishing-stage disc, typically used after coarser grits have completed bulk material removal. It is commonly used by tile setters, stone fabricators, concrete finishers, and maintenance technicians performing precision grinding on hard substrates. No vacuum holes are present, so dust extraction must be managed through the work environment rather than through the disc itself.

Key Features

• Diamond abrasive material for effective cutting on hard surfaces such as stone, tile, and carbide
• 200-grit very fine grade for finishing-stage surface refinement
• Flexible cloth backing conforms to contoured and irregular surfaces
• PSA mount for quick, secure attachment to compatible 5-inch backing pads
• No vacuum holes — suitable for dry or wet finishing applications where port-free discs are preferred
• Red disc color for easy grit identification during multi-stage finishing sequences

Compatibility

Designed for use with 5-inch PSA-style backing pads on random orbital sanders and angle grinders. Fits standard 5-inch PSA tool platforms used in stone fabrication, tile work, and concrete surface finishing.

Installation Notes

Ensure the tool is powered off and unplugged before mounting or removing the disc. Press the PSA disc firmly onto a clean, dry 5-inch backing pad to ensure full adhesive contact before operation. Inspect the disc for damage before each use and discard any disc showing tears, delamination, or worn abrasive. Follow applicable ANSI B7.1 safety standards for abrasive disc use, including the use of appropriate eye protection and guarding.
