82479 - Pferd 4-7/8 Inch Stringer Bead Wire Wheel .020 Carbon Steel 5/8-11 Hub

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.
