Norton 66261014912 Quick-change Disc 3 in Aluminum Oxide Medium

Product Description

The NORTON 66261014912 is a 3-inch non-woven aluminum oxide quick-change disc from the Bear-Tex Rapid Blend series, designed for surface blending, finishing, and light stock removal on metal and composite substrates. It mounts via a TR (Type III) attaching system, compatible with Type R quick-change tooling. The aluminum oxide grain delivers a consistent cut rate and uniform finish across the work surface. The non-woven backing and resin-bonded formula resist smearing and loading, making this disc well-suited for controlled, repeatable results at a medium grit grade. Rated to 15,000 RPM, it handles the demands of both handheld disc sanders and straight grinders used by fabricators, welders, and maintenance professionals.

This disc is built for use on a wide range of metallic and non-metallic materials, including 300 and 400 series stainless steel, brass, bronze, cast iron, ductile iron, gray iron, hard and soft carbon steels, copper, fiberglass and composite materials, super alloys, titanium, and tool steels. It is suited to applications where surface conditioning, blending weld seams, or prepping parts for coating is required. The compact 3-inch diameter makes it practical for tight-clearance work and detail areas that larger discs cannot access easily.

Compatible with 300 series stainless, 400 series stainless, brass, bronze, cast iron, ductile iron, gray iron, hard carbon steels, soft carbon steels, copper, fiberglass and composites, super alloys, titanium, and tool steels.

Installation Notes

Installation is performed by fabricators, welders, or maintenance technicians using a Type R quick-change mandrel mounted in a compatible grinder or disc sander. Verify the tool spindle speed does not exceed the 15,000 RPM disc rating before operation. Inspect the disc for damage before mounting and ensure the mandrel locking button seats fully before applying the disc to the workpiece. Follow applicable ANSI and OSHA abrasive wheel safety standards during use and wear appropriate PPE including eye protection and gloves.
