Weiler 90324 Knotted Wire End Brush 1-1/8 in Steel

Product Description

The WEILER 90324 is a knotted wire end brush designed for aggressive surface preparation, weld cleaning, and deburring on metal workpieces. It features a 1-1/8 inch brush diameter with steel knotted wire fill for maximum cutting action and durability under heavy use. The 6 mm shank mounts directly into standard rotary tools, die grinders, and drill chucks. Rated to 22,000 RPM, it handles high-speed applications without sacrificing wire retention. Wire diameter ranges from 0.0101 to 0.0200 inches, providing a balance of aggressive abrasion and consistent contact. This brush is sold individually and is a standard consumable for metal fabrication and maintenance work performed by welders, machinists, and general trade professionals.

The WEILER 90324 is suited for use on ferrous metals in both shop and field environments. Typical applications include cleaning weld seams, removing rust and scale, and preparing surfaces before coating or inspection. The hollow center construction allows it to reach into bores, ports, and recessed areas that flat or cup brushes cannot access. It fits rotary tools and die grinders accepting a 6 mm shank, making it a common choice for HVAC fabricators, pipefitters, and maintenance technicians working with steel components.

Installation Notes

Always confirm the tool RPM rating meets or exceeds the 22,000 RPM maximum before mounting. Secure the shank fully in the collet or chuck before operation and verify the workpiece is clamped or secured. Wear appropriate eye and face protection when operating wire brushes at speed. Inspect the brush for splayed or broken wires before each use and replace if wire integrity is compromised.
