Osborn 0007566500 End Brush 3/16 in Steel Crimped Wire

Product Description

The OSBORN 0007566500 is a miniature crimped wire end brush designed for precision cleaning, deburring, and surface finishing in confined areas and tight geometries. The brush features a 3/16 inch diameter with fine-grade steel crimped wire filaments up to 0.0100 inch in diameter. The crimped wire construction provides flexibility and consistent contact pressure, making it well suited for cleaning delicate parts without aggressive material removal. The brush includes a shank for use in rotary tools, die grinders, and drill presses, with a rated maximum speed of 25,000 RPM. It is not piloted, bridled, or encapsulated.

This end brush is used in light industrial, maintenance, and fabrication applications where a small brush diameter is needed to access holes, slots, ports, and recessed surfaces. Typical uses include cleaning threaded bores, removing light oxidation from metal components, and surface prep on small weldments or machined parts. It is commonly used by machinists, maintenance technicians, fabricators, and HVAC or plumbing service professionals working with small fittings and valve bodies.

Compatibility

Designed for use with rotary tools, die grinders, and drill presses accepting a standard shank-mounted end brush. Suitable for applications requiring a fine-grade steel wire end brush with a 3/16 inch diameter.

Installation Notes

Install in a compatible rotary tool or drill press chuck, ensuring the shank is fully seated and secured before operation. Confirm the tool's rated RPM does not exceed the brush's 25,000 RPM maximum. Always wear appropriate eye protection when operating wire brushes at speed. Inspect the brush for splayed or broken filaments before each use and replace if filament integrity is compromised.
