Weiler 08775 Knotted Wire Wheel Brush 6 Inch 12500 Rpm

Product Description

The WEILER 08775 is a knotted wire wheel brush designed for aggressive surface preparation, weld cleaning, and rust or scale removal on metal workpieces. The 6-inch diameter wheel uses stringer bead twist knotted carbon steel wire, which concentrates contact force along the wire tips for faster cutting action compared to crimped fill. With a rated maximum speed of 12,500 RPM, this brush is compatible with angle grinders and bench grinders equipped with a standard arbor hole mount. The 1/2-inch face width keeps abrasive contact focused, while the 1-3/8-inch trim length provides the wire flex needed to conform to irregular surfaces without premature fatigue.

This wheel brush is suited for industrial maintenance, fabrication shops, and field metalwork where light to medium deburring, slag removal, and surface conditioning are required. The arbor hole mount fits standard 5/8-inch arbor spindles, making it a common choice for both bench-mounted and portable right-angle grinder setups. It is used by ironworkers, welders, pipefitters, and general maintenance technicians. The carbon steel fill is appropriate for ferrous metal applications where wire contamination of the base material is not a concern.
