Norton 66261170273 Quick-change Disc 3 in Coarse

Product Description

The NORTON 66261170273 is a 3-inch quick-change abrasive disc from the Bear-Tex Rapid Prep series, designed for coarse surface preparation on metal and alloy workpieces. It uses a non-woven aluminum oxide construction backed by a flexible nylon web substrate. The disc mounts via a Type R (Roloc TR) attaching system and is rated for a maximum of 18,000 RPM. A premium fiber mesh, polyester backing layer, and engineered resin system work together to maintain cut rate and extend disc life under repeated use. Licensed HVAC, plumbing, and metal trades installers will find this disc well-suited to weld removal, mismatch correction, parting line cleanup, and surface blending tasks.

This disc is intended for use on die grinders in both shop and field settings. Its coarse grade and flexible backing make it effective for aggressive stock removal and surface conditioning across a wide range of ferrous and non-ferrous metals. The Type R quick-change mount allows fast disc swaps without additional hardware, reducing downtime during multi-step surface prep workflows. It is sold individually and is appropriate for professional tradespeople working with structural steel, stainless, aluminum, copper alloys, cast iron, titanium, and super alloys.
