Weiler 90287 End Brush 1/2 in Crimped Steel Wire 25000 Rpm

Product Description

The WEILER 90287 is a crimped-wire end brush designed for aggressive surface preparation, deburring, and cleaning in metalworking and fabrication applications. Built with steel fill wire in the 0.0101 to 0.0200 inch diameter range, it delivers consistent cut and resilience across a variety of workpiece materials. The 6 mm steel shank fits standard rotary tool chucks and die grinders, and the brush is rated to a maximum of 25,000 RPM. At 1/2 inch in diameter, it is well suited for accessing confined areas, ports, and bore edges where larger brushes cannot reach. Machinists, fabricators, and maintenance technicians install and use this brush in production and field service environments.

The WEILER 90287 is used in metalworking shops, manufacturing facilities, and general maintenance settings where controlled wire brushing in tight spaces is required. Typical applications include weld spatter removal, surface conditioning inside bores and holes, rust and scale removal, and light deburring on ferrous metals. The brush mounts directly to die grinders, rotary tools, and flex-shaft machines equipped with a 6 mm collet or chuck. It is sold as a single-piece unit with the shank included, requiring no additional adapter for standard 6 mm tooling.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using standard die grinders or rotary tools. Always confirm the tool spindle speed does not exceed the 25,000 RPM maximum rating of the brush before operation. Power down and de-energize the tool completely before mounting or removing the brush. Wear appropriate eye protection and gloves in accordance with applicable shop safety standards when operating wire brushes at speed.
