Norton 66623335433 Quick-change Disc 500 Grit 2 in

Product Description

The NORTON 66623335433 is a Type R quick-change non-woven abrasive disc from the Bear-Tex Rapid Prep series. It measures 2 inches in diameter and is built on a flexible nylon web backing rated at a Y-weight. The abrasive material is aluminum oxide at a 500-grit very fine grade, designed for surface prep, weld blending, and finishing work on a wide range of metals. The disc uses proprietary Clean Bond resin technology and a Vortex agglomerated aluminum oxide grain construction to deliver consistent cut and a uniform finish. Maximum operating speed is 30,000 RPM. The high-loft nylon fiber construction resists loading and helps maintain surface contact on irregular geometries.

This disc is suited for metal fabrication, maintenance, and finishing applications in both shop and field settings. Typical use cases include weld blending, deburring, light stock removal, and surface conditioning on stainless steel, carbon steel, copper, brass, bronze, cast iron, ductile iron, gray iron, titanium, tool steels, super alloys, and fiberglass or composite materials. It attaches via a Type R quick-change system and is compatible with die grinders and handheld disc sanders, making it practical for tight spaces and detailed work where a full-size grinding wheel cannot reach.
