Superior Abrasives A016838 Quick-change Disc Type R 2 in

Product Description

The SUPERIOR ABRASIVES A016838 is a Type R quick-change disc designed for surface conditioning, blending, and finishing work on metal and other hard materials. Built with an aluminum oxide non-woven construction in a medium grade, this 2-inch disc mounts via a Type R attaching system for fast, tool-free swaps on compatible die grinders and right-angle grinders. Rated to 30,000 RPM, it handles aggressive blending passes without loading. The non-woven maroon disc is suited for deburring, light rust removal, and pre-weld or pre-coat surface prep in fabrication, HVAC sheet metal, and general maintenance environments.

This disc fits applications where a small-diameter, high-speed abrasive is needed for tight access or detail work. Common use cases include sheet metal finishing in HVAC ductwork fabrication, weld seam blending, and surface prep ahead of coating or brazing. The Type R quick-change mount is standard across a wide range of compact pneumatic and electric grinders used by HVAC technicians, pipefitters, and sheet metal workers in both shop and field settings.

Inspect the backing pad and disc for damage before each use, and ensure the Type R button is fully seated and locked before operating. Always wear appropriate eye and face protection when using rotary abrasive products.
