Weiler 94672 Knotted Wire Wheel Brush 4 Inches

Product Description

The WEILER 94672 is a knotted wire wheel brush designed for aggressive surface preparation, weld cleaning, and rust or scale removal on metal workpieces. Built with carbon steel cable-twist wire, this 4-inch wheel mounts via a 5/8-11 threaded arbor connection and is rated to 20,000 RPM for use with compatible angle grinders and bench grinders. The knotted wire construction delivers concentrated cutting action, making it well suited for heavy-duty deburring, paint stripping, and surface conditioning tasks. Licensed professionals in fabrication, pipefitting, welding, and maintenance trades rely on this style of brush for fast, consistent material removal.

This wheel brush fits applications in industrial maintenance, structural steel fabrication, pipe preparation, and general metalworking. Its 1/4-inch face width and 7/8-inch trim length focus the wire contact zone for controlled, repeatable action on weld seams, rough castings, and corroded surfaces. The 5/8-11 threaded mount makes it compatible with standard right-angle grinders that accept that arbor size. It is appropriate for both shop bench work and field maintenance tasks where aggressive surface prep is required.
