OVERVIEW

Industrial-Grade Stringer Bead Cleaning

The Walter 13K654 Stringer Bead Knot Brush is a premier abrasive tool engineered for the rigorous demands of the industrial welding and fabrication sectors. Designed specifically for pipeline construction and heavy metal fabrication, this brush features a tightly twisted knot construction that delivers aggressive cleaning power in the most confined spaces. The 6-7/8 inch diameter is optimized to provide the correct peripheral speed on standard angle grinders, ensuring that the wire tips strike the workpiece with maximum force to remove slag, spatter, and oxidation effectively.

Walter Surface Technologies is renowned for its commitment to safety and performance. This wire wheel is manufactured using only the finest grade carbon steel wire, which resists fatigue and breakage even under heavy load. One of the standout features of Walter brushes is their precision balancing. Each brush is individually balanced to ensure concentricity, which significantly reduces vibration during operation. For industrial operators using these tools for extended periods, reduced vibration translates to lower risk of white finger syndrome and less operator fatigue, ultimately leading to higher productivity and safer work environments.

The "stringer bead" profile is characterized by its narrow 1/4-inch face width. This slim profile allows the brush to reach deep into V-grooves and expansion joints, making it the tool of choice for cleaning root passes in multi-pass pipe welds. Unlike wider brushes that may ride on top of the groove, the 13K654 penetrates to the bottom, ensuring a clean surface for the subsequent weld pass. This level of cleanliness is critical in preventing weld inclusions and ensuring X-ray quality welds in pressure piping and structural steel applications.

Josef Gas provides this high-performance consumable to support fabrication shops that demand reliability. Whether you are prepping surfaces for coating or cleaning inter-pass welds, the Walter 13K654 offers a consistent finish and long service life, reducing the frequency of brush changeovers and lowering overall consumable costs.

INCLUDED

  • 1 x Walter 6-7/8" Stringer Bead Knot Wire Wheel Brush (Carbon Steel)

APPLICATIONS

  • Pipe Welding: Essential for cleaning root passes and inter-pass cleaning in V-grooves.
  • Structural Steel: Removing heavy rust, scale, and mill scale from beams and plates.
  • Fabrication: Cleaning fillet welds and tight corners where wider brushes cannot reach.
  • Maintenance: Aggressive removal of paint, corrosion, and spatter on carbon steel surfaces.
  • Expansion Joints: Cleaning narrow expansion joints in concrete or metal structures.

FAQ

A stringer bead brush has a very narrow face width (knots are twisted tightly) designed specifically to fit into tight spaces like the root pass of a pipe weld or narrow V-grooves to remove slag and debris.

This wire wheel features a 5/8-inch arbor hole, making it compatible with angle grinders that support this shaft size and the 6-7/8 inch wheel diameter.

No, this brush uses carbon steel wire. Using it on stainless steel will cause 'after-rust' or contamination. For stainless steel, you should use a stainless steel wire brush (often marked with a blue hub by Walter).

The 6-7/8 inch size is a standard dimension for stringer bead brushes intended for use on 7-inch or 9-inch grinders, ensuring the brush fits within standard guards while providing optimal tip speed.

Twist knot brushes are much more aggressive than crimped wire brushes. The twisted tufts act like small hammers to impact the surface, making them ideal for removing heavy scale, weld slag, and thick rust.

Always wear a face shield (in addition to safety glasses), heavy leather gloves, and protective clothing. Wire brushes can shed wires at high speeds, so full protection is mandatory.

Walter brushes are known for their superior balancing. They are individually balanced at the factory to run smoother than many competitor brushes, reducing operator fatigue and tool wear.

Always check the stamp on the actual product plate for the specific Max RPM. Generally, brushes of this size are rated for high-speed angle grinders, but you must ensure your grinder's RPM does not exceed the brush's rating.
