Superior Abrasives A016840 Type R Quick-change Disc 2 in

Product Description

The SUPERIOR ABRASIVES A016840 is a Type R quick-change abrasive disc designed for surface finishing, blending, and light material removal. Built with aluminum oxide non-woven construction and rated at a maximum of 30000 RPM, this disc delivers consistent cut and finish control on metal, painted surfaces, and composite materials. The non-woven structure resists loading and allows the disc to conform to irregular surfaces, making it well suited for detail work and prep applications. At 2 inches in diameter, it fits compact right-angle die grinders and inline tools equipped with a Type R mandrel. Grade is Very Fine, appropriate for finishing passes rather than aggressive stock removal.

This disc is intended for use in light industrial, manufacturing, and maintenance applications where controlled surface conditioning is required. Typical scenarios include weld blending, surface prep before coating, and deburring on tight-geometry workpieces. The small 2-inch diameter allows access to restricted areas and recessed surfaces. It is used by metalworkers, fabricators, maintenance technicians, and production finishing personnel. The blue disc color and black button are characteristic of the GD series from SUPERIOR ABRASIVES.

Installation Notes

Installation and disc changes should be performed with the tool disconnected from the air supply or power source. Verify the mandrel is rated for at least 30000 RPM before mounting this disc. Inspect the disc for damage or delamination before each use and discard any disc showing visible wear beyond the usable abrasive area. Follow ANSI B7.1 and tool manufacturer guidelines for abrasive wheel mounting and operation.
