Standard Abrasives 7000046879 Quick-change Disc 3 in

Product Description

The STANDARD ABRASIVES 7000046879 is a 3-inch diameter quick-change abrasive disc designed for surface conditioning, blending, and finishing applications in metal fabrication and maintenance work. Built with aluminum oxide non-woven construction, the disc delivers consistent cut and finish without loading or glazing. It mounts via a Type R (TR) attaching system for fast, tool-free changeovers. Rated to 20,000 RPM, it suits high-speed angle grinders and die grinders commonly used in professional fab shops, welding environments, and industrial maintenance settings. The Very Fine grade makes it appropriate for light blending and pre-finishing passes rather than aggressive stock removal.

This disc is used in applications where surface prep, weld blending, or scratch refinement is required on metal substrates. The non-woven aluminum oxide construction conforms slightly to contours, making it useful for work on irregular or curved surfaces. It is a standard tool for fabricators, maintenance technicians, and metalworkers who need repeatable surface finish results with quick media changes between passes.

Compatibility

Designed for use with Type R (TR) quick-change disc backing pads on angle grinders and die grinders rated to accept 3-inch quick-change abrasive discs.

Installation Notes

Mounting and removal is performed by a metalworker or fabricator using a compatible Type R backing pad — no tools required for the disc change itself. Always ensure the grinder or die grinder is powered off and unplugged before changing discs. Verify the tool spindle speed does not exceed the 20,000 RPM disc rating before operation. Inspect the disc for damage before each use and discard any disc that shows tears, unraveling, or delamination.
