Norton 66261131617 Psa Disc 8 in 80 Grit Aluminum Oxide 100 Pack

Product Description

The NORTON 66261131617 is a pressure-sensitive adhesive (PSA) abrasive disc designed for surface preparation, stock removal, and finishing work on wood, metal, and composites. The disc measures 8 inches in diameter and features 80-grit aluminum oxide abrasive, placing it in the medium-grade range for consistent material removal without excessive surface damage. A B-weight paper backing provides a balance of flexibility and support, making it well suited for flat and slightly contoured surfaces. Each order contains 100 discs, part of the Series A275 line. Installation requires no fasteners — the PSA backing adheres directly to a compatible backup pad. This disc does not include vacuum holes.

This disc is used in shop and field applications where a PSA-style sander or grinder accepts 8-inch discs. Typical applications include paint removal, weld spatter cleanup, wood sanding between coats, and surface blending on fabrication work. The flexible paper backing conforms to the work surface under moderate pressure, which improves abrasive contact and cut rate on flat stock. At 80 grit, it bridges the gap between aggressive material removal and finish preparation, making it a common choice for intermediate sanding steps in both production and maintenance environments.

Installation Notes

Power down and disconnect the sander or grinder before mounting or removing discs. Peel the release liner and press the disc firmly and evenly onto a clean, dry backup pad to ensure full adhesive contact before use. Discard any disc that shows tears, delamination, or loss of abrasive. Follow shop safety practices including eye protection and dust control when operating abrasive equipment.
