Osborn 0003001100 Knotted Steel Wire End Brush 3/4 in

Product Description

The OSBORN 0003001100 is a knotted steel wire end brush designed for aggressive surface preparation, deburring, and cleaning in industrial and trade applications. At 3/4 inch in diameter, this end brush is mounted on a shank and rated to a maximum of 22,000 RPM, making it suitable for use with high-speed die grinders and rotary tools. The bridled construction helps control wire flare during operation, maintaining consistent cutting action throughout the working life of the brush. It is sold as a single unit. Installation is performed by machinists, fabricators, welders, and maintenance technicians.

This end brush is used for weld spatter removal, rust and scale removal, surface cleaning, and deburring on metal workpieces. The knotted wire fill provides a more aggressive cut compared to crimped wire, making it a common choice for heavy-scale removal or work on hard ferrous metals. Typical applications include prep work in welding shops, maintenance facilities, and metal fabrication environments where a compact brush profile is needed to reach bores, slots, and recessed areas.
