Standard Abrasives 7000046877 Quick-change Disc 3 in

Product Description

The STANDARD ABRASIVES 7000046877 is a 3-inch quick-change abrasive disc designed for surface conditioning, blending, and finishing operations in metal fabrication, welding prep, and general shop work. Built with aluminum oxide non-woven construction, it delivers consistent cut and finish without loading or glazing. The Type R Lockit attaching system allows fast one-handed disc changes on compatible right-angle grinders and die grinders. Rated for up to 20,000 RPM, this coarse-grade disc is suited for aggressive material removal and weld seam blending. It is sold individually and is a standard stocking item for tool cribs and shop supply programs.

This disc fits residential and commercial fabrication environments, maintenance and repair operations, and industrial production grinding applications. Typical uses include deburring, surface prep before coating or welding, and blending scratches or mill scale from steel, stainless, and aluminum workpieces. The non-woven aluminum oxide construction conforms lightly to contoured surfaces, making it useful on irregular geometry where a rigid grinding wheel would leave uneven marks. Licensed fabricators, maintenance technicians, and sheet metal workers are the primary installers and users of this product.
