Norton 66261131452 Psa Disc 600 Grit 5 in Aluminum Oxide

Product Description

The NORTON 66261131452 is a pressure-sensitive adhesive (PSA) abrasive disc designed for fine surface finishing and stock removal in professional grinding and sanding applications. Part of the A275 series, this disc features a 600-grit aluminum oxide abrasive on a B-weight paper backing, delivering consistent cut and finish on wood, metal, and composite surfaces. The PSA backing allows fast, tool-free mounting to compatible backup pads. Each pack contains 100 discs, making it practical for high-volume shop use. Weighing 0.2 pounds per pack, the unit is lightweight and easy to store and dispense at a workstation.

This disc is suited for finish sanding operations in woodworking shops, metal fabrication environments, and general manufacturing settings. The super fine 600-grit classification makes it appropriate for final prep work before sealing, coating, or polishing. The flexible paper backing conforms to slightly contoured surfaces, reducing the risk of gouging on softer substrates. No vacuum holes are included, so this disc is intended for use on solid backup pads without dust-extraction ports. It is commonly used by finish carpenters, metal fabricators, and production line workers who require repeatable, fine-surface results.

Compatibility

Designed for use with 5-inch PSA-style backup pads on random orbital and fixed-speed sanders that accept pressure-sensitive adhesive discs without vacuum holes.

Installation Notes

Ensure the backup pad surface is clean and free of debris before applying the PSA disc to achieve a secure bond. Power down the sander and disconnect it from the power source before removing or attaching any disc. Press the disc firmly and evenly onto the backup pad to prevent edge lifting during operation. Discard discs that show signs of loading, tearing, or adhesive failure to maintain consistent finish quality.
