13K404 - Walter 4-Inch Stringer Bead Wire Wheel with 5/8-11 Hub

Premium Industrial Cleaning with Walter Stringer Bead Brushes

The Walter 13K404 Stringer Bead Knot Twist Brush represents the pinnacle of surface finishing technology for industrial professionals. Designed specifically for the rigorous demands of pipeline construction and heavy fabrication, this 4-inch wire wheel is engineered to deliver aggressive cleaning power while maintaining exceptional operator safety and comfort. At the core of this tool is Walter's commitment to using only top-quality wire, which is meticulously inspected to ensure consistent tensile strength and durability. This high-grade material construction prevents premature wire breakage, a common hazard with inferior brushes, thereby enhancing safety on the shop floor.

One of the standout features of this brush is its "Perfect Balance" manufacturing process. Walter ensures that every knot is twisted and positioned with precision, resulting in a wheel that spins true without the violent vibrations often associated with angle grinder attachments. This vibration-free operation is critical for reducing operator fatigue during extended periods of use, such as cleaning long runs of pipe welds. The stringer bead profile is particularly narrow (3/16 inch), allowing the brush to penetrate deep into V-grooves and expansion joints to effectively remove slag, silica islands, and oxidation from root passes. This capability ensures a clean substrate for subsequent weld passes, reducing the risk of inclusions and weld defects.

Equipped with a standard 5/8"-11 threaded arbor, this brush mounts quickly and securely to most 4-inch and 4.5-inch angle grinders, eliminating the need for locking nuts and reducing downtime during tool changes. Whether you are removing heavy rust, descaling structural steel, or preparing surfaces for coating, the Walter 13K404 provides the consistent, high-impact performance required in professional MRO and fabrication environments.
