09C370 - Walter Allsteel 3-Inch Mounted Wire Cup Brush with 1/4-Inch Shaft

Precision Surface Preparation with Walter Allsteel

The Walter Surface Technologies 09C370 Allsteel Mounted Wire Cup Brush is engineered for professionals requiring reliable and consistent surface finishing on steel components. This 3-inch diameter brush features high-quality carbon steel wires that are crimped to provide flexibility and moderate aggression, making it an optimal choice for light to medium-duty cleaning applications. The crimped design allows the wire tips to access surface irregularities and contours more effectively than rigid knotted brushes, ensuring a uniform finish across the workpiece.

Designed with a permanently mounted 1/4-inch shaft, this brush is compatible with standard electric and pneumatic drills, as well as die grinders that accept a 1/4-inch collet. The internal construction is precision-balanced to minimize runout and vibration, which protects both the power tool bearings and the operator from fatigue during extended use. With a maximum speed rating of 4,500 RPM, it is perfectly tuned for the operational speeds of handheld drills, providing safe and controlled material removal.

This brush is specifically formulated for use on carbon steel and structural steel. It effectively removes surface contaminants such as rust, loose paint, scale, and oxidation without gouging the base metal. For industrial environments where tool longevity and finish quality are paramount, the Walter Allsteel series delivers proven performance.
