13D524 - Walter 5-Inch Crimped Wire Cup Brush with Safety Ring

Premium Surface Finishing with Walter Crimped Wire Cup Brushes

The Walter 13D524 is a high-performance 5-inch crimped wire cup brush designed to deliver superior surface cleaning results in industrial environments. Engineered by Walter Surface Technologies, this tool addresses the common challenges faced by metalworkers when using wire abrasives: safety, longevity, and consistent performance. The defining feature of this model is its integrated safety supporting ring. In standard wire brushes, centrifugal force often causes wires to splay outwards (flare) prematurely, reducing the aggressiveness of the brush and leading to wire fatigue. The Walter supporting ring constrains the wires, maintaining a tight, dense brush face that acts more effectively against contaminants.

As the brush is used and the wire tips wear down, the operator can easily remove the supporting ring. This action reveals a fresh length of wire that was previously protected, effectively regenerating the brush for a second cycle of life. This design not only maximizes the utility of the abrasive material but also ensures that the brush maintains a consistent cutting action throughout its lifespan. The crimped wire configuration is specifically chosen for applications requiring flexibility. Unlike twisted knot brushes which provide high-impact energy for heavy slag, crimped wires offer a cushioning effect, allowing the brush to conform to irregular surfaces, contours, and edges without gouging the base material.

This brush is constructed with premium oil-hardened and tempered steel wire, ensuring that each filament retains its stiffness and resistance to breakage under load. It is balanced to strict tolerances to minimize vibration, which protects the angle grinder's bearings and reduces operator fatigue during extended use. The 5/8"-11 threaded arbor ensures a secure and quick attachment to standard angle grinders. Whether used for maintenance, repair, or fabrication, the Walter 13D524 offers a cost-effective solution for surface preparation tasks.

Technical Benefits

• Controlled Flaring: The ring keeps wires aligned for maximum impact.
• Extended Lifespan: Removable ring exposes new wire, reducing replacement frequency.
• Vibration Control: Precision balancing ensures smooth operation.
