Weiler 3 in. Extra-Coarse Knotted Wire Cup Brush

The Weiler 3 in. Extra-Coarse Knotted Wire Cup Brush is engineered for demanding surface preparation, heavy-duty cleaning, and weld cleaning applications. Designed for use with right-angle grinders, this brush delivers high-impact cutting action to aggressively remove severe rust, scale, corrosion, and paint from metal surfaces. Featuring precision-engineered, evenly spaced knot holes, this cup brush prevents knotted wire tufts from shifting along the outer edge during high-speed operation. This balanced design ensures uniform brushing action, reduced operator fatigue, and an extended service life in tough workshop and industrial environments.
