Weiler 90286 End Brush Crimped Steel Wire 1/2 Inch 25000 Rpm

Product Description

The WEILER 90286 is a crimped wire end brush designed for deburring, cleaning, and surface finishing in tight spaces and hard-to-reach areas. Built with steel crimped wire filaments up to 0.010 inches in diameter, it delivers consistent scrubbing action without excessive aggressiveness. The brush measures 1/2 inch in diameter and mounts via a 6 mm steel shank, making it compatible with standard die grinders, rotary tools, and similar rotary equipment. It is rated to a maximum of 25,000 RPM. Installation and use are handled by machinists, fabricators, maintenance technicians, and metalworking professionals.

This end brush is suited for use on metal surfaces where a standard wheel or cup brush cannot reach. Typical applications include weld spatter removal, rust and scale cleaning, port cleaning, and surface prep in bores, slots, and recessed cavities. The crimped wire construction provides a moderate cut rate and is appropriate for general-purpose ferrous metal work in both shop and field maintenance environments.
