Forney Industries Inc 72756 Knotted Wire Cup Brush 6 in

Product Description

The FORNEY INDUSTRIES INC 72756 is a 6-inch knotted wire cup brush built for fast, heavy-duty cleaning and surface preparation. The knotted wire construction generates aggressive scrubbing action, making it effective for removing weld scale, rust, burrs, and heavy surface contamination. The brush features a 5/8-inch-11 arbor for secure mounting and uses 0.012-inch wire diameter. It is designed for use with high-speed air and electric tools, covering both portable and stationary machines. This type of brush is a standard tool in fabrication, welding, and metalworking trades where thorough surface prep is required before coating or further processing.

This brush is suited for large surface areas where a flat or flared cup profile can cover ground quickly. Typical applications include post-weld cleanup on structural steel, rust removal on plate or pipe, and deburring of machined edges. The 6-inch diameter makes it practical for bench grinders, angle grinders with appropriate arbor adapters, and stationary pedestal grinders. It is used in both residential shop environments and commercial fabrication settings.
