OVERVIEW

Industrial Grade Stringer Bead Cleaning

The Pferd 82494P is a premium 6-inch Stringer Bead Twist Knot Wire Brush designed for heavy-duty industrial applications. Engineered by Pferd, a global leader in abrasive and surface finishing solutions, this brush is specifically constructed to meet the rigorous demands of the pipeline and metal fabrication industries. The "stringer bead" design features a narrower face width compared to standard wire wheels, allowing the brush to penetrate deep into tight corners, V-grooves, and weld roots where standard brushes cannot reach.

Constructed with high-tensile carbon steel wire, the 82494P delivers aggressive material removal rates while maintaining a long service life. The individual wire tufts are tightly twisted into knots, providing high stiffness and impact action. This makes it the ideal tool for removing heavy slag, spatter, rust, and scale from welds, particularly after the root pass in pipe joining. The threaded 5/8-11 arbor ensures compatibility with most standard 6-inch angle grinders, allowing for quick tool changes and a secure, balanced connection that reduces vibration and operator fatigue.

For industrial procurement, the Pferd 82494P represents reliability and efficiency. Its consistent performance reduces downtime associated with frequent brush changes, while the single service pack packaging ensures that each unit remains protected until point of use. Whether for large-scale pipeline projects or general MRO tasks, this wire brush delivers the quality and safety professionals expect from the Pferd brand.

Key Applications

  • Pipeline Construction: Essential for cleaning the root pass (stringer bead) and subsequent hot passes in pipe welding.
  • Metal Fabrication: Removing heavy scale and oxidation from structural steel prior to painting or coating.
  • Maintenance & Repair: Aggressive cleaning of corroded surfaces and preparation of joints for repair welding.

FAQ

A stringer bead brush has a much narrower face width and tighter knots than a standard wire wheel. This design allows it to fit into tight spaces, such as the V-groove of a pipe weld or the root of a fillet weld, to clean the 'stringer bead' effectively.

The Pferd 82494P typically features a standard 5/8-11 UNC threaded hub, making it compatible with most 4.5-inch, 5-inch, and 6-inch angle grinders sold in North America.

This specific model uses carbon steel wire. Using carbon steel on stainless steel can cause 'after-rust' or contamination. For stainless steel applications, you should use a stainless steel wire brush (often designated with an 'INOX' label).

Always check the stamp on the actual product plate, but 6-inch stringer bead brushes typically have a maximum RPM rating around 9,000 to 12,500 RPM. Never exceed the Max RPM rating marked on the brush.

The individual wires are twisted together into tufts or 'knots'. This twisting supports the wire tips, making the brush much stiffer and more aggressive compared to crimped wire brushes, which are better for lighter surface finishing.

Yes, absolutely. Wire brushes can throw loose wires and debris at high speeds. Always wear ANSI-approved safety glasses, a face shield, heavy gloves, and protective clothing (like a leather apron) when operating wire brushes.

Yes, the aggressive twist knot design is very effective at removing old paint, coating, and heavy corrosion from metal surfaces, though it may leave a rougher finish than a crimped wire brush.

It indicates that the brush is packaged individually, often in a box or clamshell, rather than in bulk loose packaging. This protects the threads and wires during shipping and storage.
