Tru-maxx 88546 Wheel Brush 5 in Carbon Steel Stringer Bead

Product Description

The TRU-MAXX 88546 is a 5-inch diameter wheel brush designed for aggressive surface conditioning, weld cleaning, and scale removal on metal workpieces. It features stringer bead twist wire knots made from carbon steel filaments in the 0.0200 to 0.0299 inch diameter range, delivering consistent cutting action on welds, rust, and mill scale. The brush mounts via a threaded 5/8-11 arbor hole and is rated to 12,500 RPM, making it suitable for use on angle grinders and bench grinders used in fabrication, maintenance, and industrial cleaning applications. It is installed and operated by welders, pipefitters, millwrights, and maintenance technicians.

This wheel brush is built for weld bead cleaning, deburring, and surface preparation on carbon steel and ferrous metal components. The stringer bead wire configuration concentrates contact force at the wire tips, which improves effectiveness on tight weld seams and irregular surfaces. With a 3/16 inch face width and 7/8 inch trim length, it fits standard arbor-mount angle grinders and is well suited to shop fabrication benches, field pipe work, and structural steel maintenance tasks.

Installation Notes

Installation and operation of this brush should be performed by trained personnel familiar with rotary abrasive tool safety. Always confirm the grinder spindle speed rating meets or exceeds 12,500 RPM before mounting. Power down and disconnect the grinder from all power sources before mounting or removing the brush. Wear appropriate PPE including face shield, gloves, and hearing protection during operation, and inspect the brush for wire fatigue or damage before each use.
