Weiler 90307 End Brush 3 in Stainless Steel Crimped Wire

Product Description

The WEILER 90307 is a 3-inch diameter end brush designed for surface preparation, deburring, and cleaning in industrial and trade applications. It features crimped stainless steel wire fill with filament diameters up to 0.0100 inch, providing aggressive scrubbing action on metal surfaces without introducing carbon contamination. The brush includes a 6 mm shank and is rated to a maximum of 16,000 RPM, making it compatible with standard die grinders and rotary tools. It is used by fabricators, pipefitters, machinists, and maintenance technicians who need precise brushing action in confined or hard-to-reach areas.

This end brush is suited for use on stainless steel, aluminum, and other metal workpieces where contamination control matters. The crimped wire construction allows for moderate flexibility and consistent contact on irregular or curved surfaces. Typical applications include weld cleanup, tube and pipe end preparation, casting deburring, and light surface conditioning. It ships as a single unit and is intended for professional shop and field use.
