Norton 66261170274 Quick-change Disc 4in Coarse Non-woven

Product Description

The NORTON 66261170274 is a coarse-grade, non-woven quick-change abrasive disc from the Bear-Tex Rapid Prep series, designed for aggressive surface preparation on metal workpieces. The disc measures 4 inches in diameter with a nylon web backing and a flexible construction that allows it to conform to contoured surfaces. It attaches via a Type R (Roloc TR) quick-change system for fast mounting and removal on die grinders. Rated to 15,000 RPM maximum, it is built for weld removal, mismatch correction, parting line removal, and surface blending. The engineered resin system and premium fiber mesh backing contribute to extended cut rate and disc life compared to standard non-woven constructions.

This disc is suited for use on die grinders in both shop and field environments. It is commonly used in fabrication, welding, and finishing operations where rapid surface conditioning is required. The aluminum oxide abrasive material makes it appropriate for a wide range of metals including stainless steel, carbon steels, aluminum, brass, bronze, copper, cast iron, ductile iron, titanium, and super alloys. It is sold as an individual replacement disc, making it practical for technicians who need to swap out worn discs without purchasing a full kit.

Installation Notes

Install and remove the disc by pressing and twisting onto a compatible Type R quick-change arbor — ensure the arbor is rated for the disc diameter and RPM before use. Always verify the tool spindle speed does not exceed the disc maximum RPM rating before operation. Wear appropriate eye protection and gloves during disc changes and grinding operations. Inspect the disc for damage or wear before each use and discard any disc that shows tearing, delamination, or uneven wear.
