Osborn 0003074700 End Brush 1 in Stainless Knotted Wire

Product Description

The OSBORN 0003074700 is a knotted wire end brush designed for aggressive surface preparation, deburring, and cleaning in tight spaces and bore openings. Built with stainless steel fill wire in the 0.0101 to 0.0200 inch diameter range, this brush delivers consistent cutting action on metal surfaces where flexible tool access is required. The knotted wire construction provides higher abrasive force compared to crimped styles, making it well suited for weld cleaning, rust removal, and scale removal. Rated to 20,000 RPM, it mounts via an included shank to standard rotary tools, die grinders, and drill chucks used by fabricators, pipefitters, and maintenance technicians.

This end brush is used in industrial maintenance, metal fabrication, and pipe preparation applications. It fits easily into tube ends, port openings, and confined weld joints where cup or wheel brushes cannot reach. The 1 inch brush diameter keeps the tool compact for precision work in restricted access areas. It is a single-piece unit with no bridling, piloting, encapsulation, or flare, keeping the design straightforward for general-purpose rotary tool use in both shop and field environments.

Key Features

• Knotted wire construction delivers higher cutting force than crimped wire for demanding deburring and cleaning tasks
• Stainless steel fill wire resists corrosion and is suitable for use on stainless workpieces without contamination risk
• 1 inch brush diameter sized for bore, tube, and confined joint access
• Rated to 20,000 RPM for use with high-speed die grinders and rotary tools
• Shank included for direct chuck or collet mounting with no adapter required
• Non-bridled, non-encapsulated design for straightforward replacement and setup

Compatibility

Designed as a direct-mount end brush for die grinders, rotary tools, and drill chucks accepting a standard shank. Suitable for use on ferrous and stainless steel workpieces in fabrication and maintenance applications.

Installation Notes

End brushes must be installed with the rotary tool fully powered off and the collet or chuck completely secured before operation. Verify the tool spindle RPM rating meets or exceeds the 20,000 RPM maximum rating of this brush before use. Always wear appropriate eye protection and follow ANSI B11 or applicable shop safety standards when operating wire brushes at speed. Inspect the brush for wire fatigue or deformation before each use and replace if fill wires show significant wear or distortion.
