Weiler 90302 End Brush 1-1/2 in Crimped Steel Wire 20000 Rpm

Product Description

The WEILER 90302 is a crimped steel wire end brush designed for surface preparation, deburring, blending, and cleaning tasks on metal workpieces. The brush measures 1-1/2 inches in diameter and mounts via a 6 mm shank that is included with the unit. Crimped wire construction provides a flexible, consistent cut action suited for contoured and irregular surfaces. The flared fill geometry allows the wire tips to make broad contact with the work surface. Rated to a maximum of 20,000 RPM, this end brush is built for use in die grinders and similar high-speed rotary tools commonly operated by machinists, fabricators, and maintenance technicians.

This end brush is suited for light to medium stock removal, rust and scale removal, weld spatter cleanup, and surface finishing on steel, cast iron, and similar hard materials. It is appropriate for both shop and field use wherever a die grinder or compatible rotary tool is available. The 6 mm shank fits standard collets found on most pneumatic and electric die grinders. Applications span industrial fabrication, HVAC sheet metal work, plumbing rough-in prep, and general mechanical maintenance environments.

Installation Notes

This brush is installed and operated by machinists, fabricators, or maintenance technicians using a die grinder or compatible rotary tool. Before mounting, confirm the tool collet size matches the 6 mm shank and that the tool's rated speed does not exceed the 20,000 RPM maximum marked on the brush. Always wear appropriate eye and face protection when operating wire end brushes. Inspect the brush for damaged or broken wires before each use and replace if wear or deformation is observed.
