Norton 66261170287 Quick-change Disc 4in Aluminum Oxide Medium

Product Description

The NORTON 66261170287 is a quick-change non-woven abrasive disc from the Bear-Tex Rapid Prep series, designed for surface conditioning, mild weld removal, and blending operations on a wide range of metals. It mounts via a Type R (Roloc TR) quick-change attaching system and is rated to a maximum of 12,000 RPM. The disc measures 4 inches in diameter and is backed by a flexible nylon web with a polyester backing layer and an engineered resin bond system. The medium-grade aluminum oxide abrasive delivers consistent cut rate and extended disc life compared to standard non-woven products. Licensed HVAC, metalworking, and general trade technicians will find this disc suited to die grinder applications requiring controlled surface finishing.

This disc is intended for use on die grinders in both shop and field environments. Its flexible construction allows it to conform to irregular or contoured surfaces during blending and finishing passes. Rated material applications include 300 Series Stainless, 400 Series Stainless, Aluminum, Brass, Bronze, Cast Iron, Copper, Ductile Iron, Gray Iron, Hard Carbon Steels, Soft Carbon Steels, Super Alloys, and Titanium. The maroon color indicates a medium-coarse cut, appropriate for mild stock removal, weld seam blending, and pre-paint or pre-coat surface prep workflows.
