Norton 66261131495 Psa Disc 150 Grit 5 Inches 100 Pack

Product Description

The NORTON 66261131495 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface finishing, sanding, and preparation work on wood, metal, and composite materials. Part of the Norton A275 series, this disc measures 5 inches in diameter and carries a 150 grit rating, placing it in the very fine grade range. The aluminum oxide abrasive grain delivers consistent cutting action and extended service life. Paper backing with a B-weight construction provides a balance of flexibility and durability suited to both flat and slightly contoured surfaces. These discs are installed by trades professionals and skilled woodworkers using random orbital and disc sanders.

This disc is well suited to finish sanding operations in cabinet shops, flooring applications, automotive body work preparation, and general metalworking environments. The PSA backing allows quick, secure mounting to compatible foam or hard sanding pads without the need for hook-and-loop hardware. The disc includes 5 vacuum holes to support dust extraction systems, keeping the work surface clear and extending abrasive life. Each pack contains 100 discs for production-level use.

Compatibility

Designed as a PSA-style replacement disc compatible with 5-inch PSA sanding pads and random orbital sanders that accept pressure-sensitive adhesive abrasive discs with a 5-vacuum-hole dust extraction pattern.

Installation Notes

Installation is performed by removing the release liner from the PSA backing and pressing the disc firmly onto a clean, dry sanding pad. Power down the sander and disconnect it from the power source before changing discs. Ensure the pad surface is free of adhesive residue from previous discs to maintain proper seating and balance. Discs should not be reattached once removed, as the adhesive bond degrades after initial use.
