Weiler 94057 Stringer Bead Wheel Brush 4.5 in Carbon Steel

Product Description

The WEILER 94057 is a stringer bead twist wire wheel brush designed for aggressive weld cleaning, rust removal, and surface preparation on metal. The brush features a 4.5-inch outside diameter and is filled with carbon steel wire in the stringer bead knot configuration, which concentrates wire tips for deep cleaning in weld beads and tight grooves. It mounts via a threaded 5/8-11 arbor with a dual hex nut hole style and is rated to 15,000 RPM, making it suitable for use on right-angle grinders. No shank is included. Fabricators, pipefitters, and ironworkers use this brush as a standard prep and cleanup tool in both shop and field applications.

This wheel brush is used in metal fabrication, structural steel work, pipeline work, and heavy equipment repair where weld spatter, mill scale, and corrosion must be removed from steel surfaces. The stringer bead wire construction is particularly suited for cleaning weld passes between multi-pass welds and for working into narrow channels where flat wire knots have limited reach. It is appropriate for both shop use on fixed grinder stations and field use with portable right-angle grinders.
