13K414 - Walter 4-Inch Stainless Steel Stringer Bead Wire Wheel 5/8 Arbor

Premium Stainless Steel Wire Brush for Precision Cleaning

The Walter 13K414 is a high-performance 4-inch Stringer Bead Knot Twisted Brush designed specifically for the rigorous demands of industrial metalworking. Manufactured by Walter Surface Technologies, a leader in abrasive and tooling solutions, this brush is engineered to deliver superior results when working with stainless steel and aluminum materials. The core advantage of this tool lies in its meticulous construction; each tuft of wire is tightly knotted and precisely positioned to ensure perfect rotational balance. This attention to detail eliminates the vibration often associated with standard wire brushes, resulting in smoother operation, reduced tool wear, and significantly less operator fatigue.

Designed with a narrow 3/16-inch face width, the stringer bead profile is the industry standard for cleaning root pass welds in pipeline construction and fabrication. It allows the operator to reach deep into narrow grooves and tight corners where wider brushes cannot access. The knot twisted construction provides a high-impact, aggressive cleaning action that effectively removes slag, spatter, and heavy oxidation without removing base material. Because it is constructed with high-quality stainless steel wire, it is safe for use on stainless steel parts, preventing the cross-contamination that leads to after-rust.

Durability is a hallmark of the Walter brand. The 13K414 features improved construction that secures the wire knots firmly in place, ensuring maximum safety even at high rotational speeds. Whether you are prepping surfaces for welding or cleaning up after the bead is laid, this brush offers the reliability and performance required for professional environments. It mounts easily to standard angle grinders with a 5/8-inch arbor, making it a versatile addition to any welder's toolkit.
