OVERVIEW

Heavy-Duty Stringer Bead Cleaning

The Walter 13L604 is a high-performance 6-inch twist knot wire wheel brush engineered for the most demanding industrial applications. Specifically designed as a "stringer bead" brush, it features a narrow 3/8-inch face width that allows it to penetrate deep into V-grooves and expansion joints, making it an essential tool for pipeline welders and fabricators. The brush is constructed with premium oil-hardened and tempered carbon steel wire, ensuring consistent aggression and a long service life even under heavy load.

Precision Balanced for Safety

Vibration is a major concern in handheld grinding operations. Walter Surface Technologies manufactures these brushes with individual knot balancing, ensuring that every wheel runs smoothly and concentrically. This precise balance significantly reduces operator fatigue (HAVS) and prevents premature wear on angle grinder bearings. The integrated 5/8"-11 threaded arbor allows for fast, tool-free mounting on standard angle grinders, ensuring a secure fit that improves safety and efficiency on the job site.

Technical Specifications

This brush is rated for a maximum speed of 9,000 RPM, optimized for use with 6-inch angle grinders. The twisted knot design provides high-impact action, effectively removing heavy slag, thick rust, scale, and spatter without removing base material. It is the ideal choice for inter-pass cleaning during multi-pass welding operations, particularly in the oil and gas industry where weld integrity is paramount.

FAQ

This brush comes with a standard 5/8"-11 threaded arbor, fitting most North American 4.5", 5", and 6" angle grinders.

No, this brush uses carbon steel wire. Using it on stainless steel can cause cross-contamination and rust issues. You should use a stainless steel wire brush (typically marked with a blue hub or label) for stainless applications.

The maximum safe operating speed is 9,000 RPM. Ensure your grinder does not exceed this speed.

A stringer bead brush has a very narrow face (like this 3/8" model) designed specifically to fit into the narrow groove of a pipe weld to clean the root pass or inter-pass slag.

No, the brush has a built-in threaded hub that screws directly onto the grinder's spindle.

For heavy removal, yes. Twisted knot brushes are stiffer and more aggressive than crimped brushes, making them better for heavy slag, thick rust, and hard scale.
