Norton 66261016994 Quick-change Disc 3in Aluminum Oxide

Product Description

The NORTON 66261016994 is a 3-inch diameter, non-woven quick-change disc from the Bear-Tex Rapid Prep series, designed for surface conditioning and finishing on metal and composite materials. It mounts via a TR (Type III) / Type R attaching system and is rated to 20000 RPM. The disc features an aluminum oxide abrasive grain on a flexible polyester and nylon web backing. Extra coarse grade delivers moderate material removal with a clean, smear-free surface finish. It is installed by metalworking fabricators, pipefitters, maintenance technicians, and other trade professionals who need fast disc changes on die grinders and handheld disc sanders.

This disc is suited for surface prep, blending, and conditioning tasks across a wide range of base materials. Rated applications include 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. The flexible backing conforms to contoured and irregular surfaces, making it practical for weld blending and pre-inspection cleanup in both shop and field environments. Compatible machines include die grinders and handheld disc sanders equipped with a TR or Type R quick-change interface.
