Norton 66623303912 Quick-change Disc 2in Ceramic Extra Coarse

Product Description

The NORTON 66623303912 is a 2-inch ceramic alumina non-woven quick-change abrasive disc from the Bear-Tex Blaze Rapid Blend series. It mounts via a Type R Speed-Lok TR attachment system and is rated for a maximum of 30,000 RPM. The disc carries an Extra Coarse grade and features an open web, non-woven construction that resists loading during aggressive material removal. Blaze ceramic grain technology delivers fast, consistent cut rates across a wide range of metals. This disc is designed for use with handheld disc sanders and straight grinders in fabrication, maintenance, and finishing workflows.

This disc is suited for metal surface conditioning, blending, and light stock removal on a variety of materials including 300 and 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It fits standard Type R quick-change attachment systems, making tool-free disc swaps fast in production or field environments. The rigid backing maintains consistent contact across flat and low-contour surfaces.
