13W302 - Walter Allsteel 3-Inch Crimped Wire Cup Brush with 5/8-11 Thread

Precision Cleaning with Walter Allsteel Wire Cup Brushes

The Walter Allsteel™ 3-inch Crimped Wire Cup Brush (SKU: 13W302) is a premium abrasive tool designed for surface preparation and finishing on steel components. Engineered by Walter Surface Technologies, this brush exemplifies the brand's commitment to safety, performance, and longevity. The 13W302 features high-grade, oil-hardened, and tempered steel wires that are crimped to provide flexibility. This design allows the brush to conform to irregular contours and shapes, making it an excellent choice for light-to-medium duty cleaning tasks where preserving the base material surface finish is a priority.

One of the standout features of the Allsteel line is the meticulous manufacturing process that ensures perfect rotational balance. An unbalanced wire brush can cause severe vibration, leading to operator fatigue (HAVS) and premature wear on the angle grinder's bearings. Walter guarantees that every 13W302 brush runs smooth and true, enhancing user comfort and control. The integrated 5/8"-11 threaded arbor allows for direct, tool-free mounting onto standard angle grinders, ensuring a secure connection that handles high RPMs safely.

This brush is specifically formulated for use on carbon steel. The crimped wire action is ideal for removing surface rust, peeling paint, light scale, and weld discoloration. Unlike twisted knot brushes which are designed for high-impact aggression, the crimped style offers a softer touch, cleaning the surface effectively without digging in. Whether you are prepping a surface for painting, cleaning up after welding, or maintaining industrial equipment, the Walter 13W302 delivers consistent, reliable results.
