Weiler 90370 End Brush 0.75 in Steel Crimped Wire

Product Description

The WEILER 90370 is a steel crimped wire end brush designed for surface preparation, cleaning, and deburring work on metal components. Measuring 0.75 inches in diameter, it mounts to rotary tools, die grinders, or drill chucks and spins up to 22,000 RPM, making it suitable for high-speed material removal in tight or recessed areas. The crimped wire fill provides a consistent, flexible action that conforms to irregular surfaces without excessive loading. Machinists, fabricators, and maintenance technicians reach for this brush when they need reliable performance in confined spaces where cup or wheel brushes cannot reach.

The WEILER 90370 is suited for light to moderate cleaning and finishing tasks on steel, cast iron, and similar metal substrates. It is commonly used in metal fabrication shops, maintenance facilities, and manufacturing environments where deburring weld spatter, removing rust, and surface conditioning are routine operations. The brush is sold individually and works with standard rotary tool shanks compatible with its mounting configuration.
