Norton 66623335436 Quick-change Disc 500 Grit 3 in

Product Description

The NORTON 66623335436 is a quick-change abrasive disc from the Bear-Tex Rapid Prep series, engineered for surface preparation, weld blending, and finishing operations on a wide range of metals and composites. Built on a flexible nylon web backing, this disc uses Vortex agglomerated aluminum oxide grain bonded with a proprietary Clean Bond resin technology. At 500 grit, it falls in the very fine grade range, making it well suited for light material removal and final surface conditioning. The Type S attaching system allows fast, tool-free disc changes on compatible handheld disc sanders and straight grinders. Maximum operating speed is 20,000 RPM.

This disc is designed for use on metals and composite materials including 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. It is commonly used by fabricators, welders, maintenance technicians, and metalworkers who require a consistent, fine finish without switching to a separate tool. The 3-inch diameter fits standard quick-change spindle pads used with handheld disc sanders and straight grinders.
