Norton 66261170286 Quick-change Disc 3in Aluminum Oxide

Product Description

The NORTON 66261170286 is a Type R quick-change non-woven abrasive disc from the Bear-Tex Rapid Prep series, designed for surface conditioning, weld blending, and light material removal on a wide range of metals. The disc measures 3 inches in diameter and attaches via a Type R (Roloc TR) button system for fast, tool-free changes on compatible die grinders. Built on a flexible nylon web backing with a premium polyester fiber mesh and an engineered resin bond system, it delivers consistent cut rate and extended disc life. Rated at a maximum of 18,000 RPM, this medium-grade aluminum oxide disc is well suited for controlled, repeatable surface prep work in fabrication and maintenance environments.

This disc is intended for use on die grinders in both shop and field settings. Its flexible construction makes it effective on contoured and flat surfaces alike. Compatible materials include 300 and 400 series stainless steel, aluminum, brass, bronze, copper, cast iron, ductile iron, gray iron, hard and soft carbon steels, super alloys, and titanium. Typical applications include mild weld removal, surface blending, and pre-finish conditioning where a non-woven abrasive is preferred over coated alternatives. Each package contains one disc.

Installation Notes

This disc is installed and removed by a metalworker or fabricator using a compatible Type R die grinder mandrel — no tools required for the disc change itself. Before mounting or removing the disc, ensure the grinder is fully powered off and the disc has come to a complete stop. Always verify the tool spindle speed does not exceed the 18,000 RPM disc rating before operation. Inspect the disc for damage or delamination before each use and replace if any defects are present.
