Norton 66623335427 Quick-change Disc 120 Grit 2 in

Product Description

The NORTON 66623335427 is a non-woven quick-change abrasive disc from the Bear-Tex Rapid Prep series, designed for surface preparation, weld blending, and finishing across a wide range of metals. Built on a flexible nylon web backing with a Y-weight rating, it uses vortex agglomerated aluminum oxide grain bonded with proprietary Clean Bond resin technology. The high-loft nylon fiber construction delivers consistent cut and surface contact without loading. Rated to 20,000 RPM maximum operating speed, this disc runs on TR (Type III) / Type R quick-change systems and is sized at 2 inches in diameter for use in tight spaces and detail work.

This disc is suited for use in fabrication shops, maintenance environments, and field service applications where surface finishing on ferrous and non-ferrous metals is required. It attaches to die grinders and handheld disc sanders equipped with a Type R or TR (Type III) quick-change arbor. The medium grade, 120 grit specification makes it appropriate for blending welds, removing light oxidation, and prepping surfaces before coating. It performs on 300 and 400 series stainless steel, brass, bronze, cast iron, copper, ductile iron, fiberglass and composites, gray iron, hard and soft carbon steels, super alloys, titanium, and tool steels.
