Norton 66254487446 Psa Disc 6 in 80 Grit Silicon Carbide 100pk

Product Description

The NORTON 66254487446 is a pressure-sensitive adhesive (PSA) abrasive disc designed for stock removal and surface preparation on a wide range of materials. The disc measures 6 inches in diameter and uses 80-grit silicon carbide abrasive, placing it in the medium-grade cutting range. A lightweight B-weight paper backing provides flexibility across contoured and flat surfaces. The disc mounts directly to PSA-compatible random orbital and disc sanders without fasteners or clamps, making changeovers fast during production work. This item is sold as a pack of 100 discs, part of the NORTON A413 series.

This disc is suited for dry sanding applications on wood, composite materials, and certain non-ferrous surfaces. The silicon carbide grain cuts aggressively on harder, brittle materials and breaks down in a controlled pattern to expose fresh cutting edges throughout the disc life. The 6-inch format fits standard PSA disc pads common in woodworking shops, finishing operations, and light industrial production environments. No vacuum holes are present, so this disc is intended for use on solid-face backing pads rather than dust-extraction platforms.

Installation Notes

Ensure the backing pad surface is clean and free of adhesive residue before applying each disc. Peel the release liner and align the disc flat against the backing pad before pressing firmly from center to edge to eliminate air pockets. Discard any disc showing tears, loading, or loss of abrasive before continuing work. Follow all machine manufacturer guidelines and applicable shop safety procedures when operating disc sanders.
