Osborn 0003070700 End Brush 1 in Steel Crimped Wire

Product Description

The OSBORN 0003070700 is a steel crimped wire end brush with a 1-inch brush diameter, rated for a maximum of 20,000 RPM. End brushes mount in rotary tools, die grinders, and drill chucks to deliver aggressive surface finishing in tight or confined areas. The crimped wire construction flexes under load while maintaining consistent contact pressure, making this brush suited for deburring, cleaning, and light material removal on metal surfaces. It is not piloted, bridled, encapsulated, or flared. Machinists, fabricators, maintenance technicians, and welders are the typical users of this brush style.

This end brush is designed for use in applications where a straight or cup-style wheel cannot reach — weld joints, tube interiors, bores, slots, and recessed surfaces. It is well suited to metal prep work in fabrication shops, maintenance and repair operations, and general industrial cleaning tasks. The steel wire fill material makes it appropriate for use on ferrous metals, cast iron, and structural steel where aggressive action is needed.

Compatibility

Designed as an OEM-style end brush for use with standard die grinders, rotary tools, and drill chucks that accept end brush shanks; confirm your tool RPM rating meets or exceeds the 20,000 RPM maximum before use.

Installation Notes

End brushes should be installed by a qualified operator familiar with rotary tool safety practices. Always confirm the tool spindle speed does not exceed the 20,000 RPM maximum rating of the brush before operation. Secure the shank fully in the collet or chuck and inspect the brush for damaged or broken wire fill before each use. Wear appropriate personal protective equipment including eye protection when operating rotary wire brushes.
