PFERD 82613 6" Stringer Bead Knot Wire Wheel Brush .020" SS Wire 5/8-11 Thread 56 Knots

The PFERD 82613 is a 6-inch stringer bead knot wire wheel brush designed for heavy-duty surface conditioning, deburring, and cleaning operations. Featuring .020" stainless steel wire twisted into tight stringer bead knots, this wheel delivers the most aggressive brushing action available in wire wheel technology — making it ideal for demanding industrial applications such as pipeline and container construction.

With a 5/8-11 threaded arbor and 56 individual knots, this brush mounts directly to standard angle grinders and provides consistent, uniform contact across the work surface. The stringer bead knot configuration concentrates wire tips for maximum impact and cutting action, outperforming standard crimped or twisted wire styles on tough materials.
