OVERVIEW

Industrial Grade Stringer Bead Cleaning

The Pferd 82479 Knot Wheel is a premium industrial abrasive tool designed specifically for the rigorous demands of the pipeline and metal fabrication industries. This 4-7/8 inch stringer bead brush is engineered with a tightly twisted knot construction, featuring 38 individual knots. This high knot count creates a significantly denser brush face compared to standard wire wheels, delivering aggressive impact action that is essential for removing heavy slag, spatter, and oxidation from weld seams.

Manufactured with .020-inch tempered carbon steel wire, this brush offers exceptional stiffness and durability. The stringer bead profile is deliberately narrow, allowing the brush to penetrate deep into V-grooves and expansion joints where wider brushes cannot reach. This makes it the tool of choice for cleaning root passes and hot passes in pipe welding applications. The integrated 5/8-11 threaded nut simplifies tool changes, allowing operators to mount the brush directly onto standard angle grinders without the need for additional adapters or locking nuts.

Pferd is renowned for their attention to balance and concentricity. The 82479 model is precision-balanced to ensure smooth operation, which reduces wear on the power tool bearings and minimizes operator fatigue caused by vibration. For industrial supply managers and procurement specialists, this brush represents a reliable, high-performance solution that reduces downtime associated with frequent brush changes. It is compatible with most 4-1/2 inch, 5-inch, and 6-inch angle grinders, provided they accommodate the 5/8-11 spindle and appropriate safety guards.

FAQ

The Pferd 82479 features a standard 5/8-11 UNC threaded arbor, making it compatible with most North American 4-1/2", 5", and 6" angle grinders.

No, you should not use carbon steel brushes on stainless steel as it can leave carbon deposits that lead to rust and corrosion (after-rust). Use a stainless steel wire brush for stainless applications.

A stringer bead brush has a very narrow face width and tightly twisted knots. It is designed specifically to fit into tight spaces like the bevel of a pipe weld or the root pass groove to clean out slag and debris.

Always refer to the label on the actual product for the certified Max RPM. Generally, 4-7/8" brushes are rated for high speeds suitable for angle grinders, but you must ensure your grinder's RPM does not exceed the brush's rating.

The high knot count (38) provides a denser wire face compared to standard 30-knot wheels. This results in more wire tips in contact with the work surface, providing more aggressive cleaning and longer brush life.

Absolutely. Wire brushes can throw wire filaments during use. Always wear ANSI-approved safety glasses, a face shield, heavy gloves, and protective clothing (apron/sleeves) when operating wire wheels.

Yes, the aggressive .020" carbon steel wire is very effective at removing paint, rust, and heavy scale from steel surfaces.

It fits angle grinders with a 5/8-11 spindle. While the diameter is 4-7/8", it is commonly used on 5-inch and larger grinders. Ensure your grinder guard can accommodate the brush size safely.
