Forney Industries Inc 72753 Knotted Wire Cup Brush 4 Inches

Product Description

The FORNEY INDUSTRIES INC 72753 is a 4-inch knotted wire cup brush built for fast, heavy-duty cleaning of large surfaces. The knotted wire configuration delivers aggressive action for removing weld scale, rust, and burrs from metal workpieces. Wire diameter is 0.012 inches, providing the stiffness needed for tough surface prep without sacrificing control. The 5/8-11 arbor fitting makes it compatible with a wide range of angle grinders and cup brush tools. Licensed trades and fabrication shops use this brush as part of standard weld prep and metal finishing workflows.

This cup brush is designed for use in high-speed air and electric tools, covering both portable and stationary machines. It is well suited to industrial fabrication environments, maintenance shops, and structural steel work where large surface areas require rapid scale or rust removal before coating, welding, or inspection. The 4-inch diameter allows good surface coverage in a single pass, reducing total working time on flat or mildly contoured metal surfaces. Package quantity is 10 units.
