OVERVIEW

Precision Cleaning for Recessed Surfaces

The Walter 3/4" Knotted Wire End Brush (Style 4491) is an industrial-grade abrasive tool designed for heavy-duty surface preparation and finishing. Engineered by Walter Surface Technologies, this brush utilizes premium carbon steel wires twisted into tight knots, providing a stiff and aggressive brushing action capable of removing stubborn contaminants such as heavy rust, scale, paint, and corrosion.

End brushes are specifically designed to address the challenges of cleaning hard-to-reach areas. The 3/4-inch diameter profile makes this tool essential for working inside pipes, cleaning internal diameters, deburring holes, and accessing recessed corners that larger wheel or cup brushes cannot reach. The knotted construction prevents the wires from flaring out prematurely under load, ensuring consistent performance and extending the lifespan of the brush even under rigorous use.

Safety and balance are paramount in the design of Walter wire brushes. This unit features a standard 1/4-inch shank, making it compatible with most pneumatic and electric die grinders. The brush is precision-balanced to run smoothly at high RPMs, reducing vibration that can damage power tools and cause operator fatigue (HAVS). Whether used for mold cleaning, casting cleanup, or general maintenance, this end brush delivers reliable, high-impact cleaning power.
