Osborn 0003011800 End Brush 1/2 in Steel Crimped Wire

Product Description

The OSBORN 0003011800 is a crimped wire end brush designed for surface preparation, deburring, and cleaning in metalworking and fabrication applications. Built with a 0.5-inch diameter steel fill, this brush mounts via an included shank and connects directly to a rotary tool, drill, or die grinder. It is bridled for added wire retention and shape control during operation. Maximum rated speed is 25,000 RPM, making it suitable for high-speed finish and cleaning passes on metal surfaces. The steel crimped wire construction delivers consistent scrubbing action without the aggressive cut of knotted wire brushes.

This end brush is used in industrial maintenance, metal fabrication, and general shop work where a small-diameter brush profile is needed to access bores, ports, slots, and recessed surfaces. Typical applications include weld spatter removal, rust and scale cleaning, paint stripping from tight areas, and light deburring on steel and iron workpieces. It is suited for use by machinists, maintenance technicians, fabricators, and tool-and-die professionals working with rotary power tools.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using standard rotary tool or drill chuck procedures. Ensure the tool is fully powered down and unplugged before mounting or removing the brush. Confirm the tool's rated RPM meets or does not exceed the brush's 25,000 RPM maximum before operating. Always use appropriate eye protection and follow applicable shop safety standards when operating wire brushes at high speeds.
