Norton 662544-68388 Avos Sanding Disc 5x7/8 Inches Sg Blaze F980

Product Description

The NORTON 662544-68388 is an AVOS sanding disc engineered for aggressive material removal and long service life on demanding grinding and finishing applications. Built on the SG Blaze F980 platform, this disc uses seeded gel abrasive grain that fractures along controlled crystalline planes, continuously exposing fresh cutting edges as the disc wears. Each disc measures 5 inches in diameter with a 7/8-inch arbor hole, fitting standard random-orbit and angle grinder backing pads used in metal fabrication, weld grinding, and surface preparation work. The case contains 10 discs per box across 40 discs per case, making it a practical stocking unit for shops and service vehicles.

This sanding disc is suited for metal fabrication shops, automotive body work environments, and industrial maintenance settings where consistent cut rate and disc longevity matter. The AVOS attachment system integrates a built-in speed-safe hub that allows tool-free disc changes on compatible AVOS-style grinders, reducing downtime during high-volume surface preparation tasks. Licensed tradespeople and experienced fabricators working on steel, stainless, and exotic alloys will find this disc appropriate for both production grinding and finishing passes.
