Weiler 90288 End Brush 0.5 in Crimped Steel Wire 25000 Rpm

Product Description

The WEILER 90288 is a crimped-wire end brush designed for deburring, cleaning, and surface preparation on metal and other hard materials. The brush head measures 0.5 inches in diameter and is filled with crimped steel wire in the 0.0101 to 0.0200 inch diameter range, delivering aggressive scrubbing action with controlled flexibility. A 6 mm steel shank provides secure chuck retention in die grinders, drill presses, and rotary tools. Rated to a maximum of 25,000 RPM, this end brush suits high-speed power tool applications where precision access to bores, ports, and recessed surfaces is required. Metalworking professionals, maintenance mechanics, and fabrication shops are the primary users.

This end brush is suited for use in tight-access areas where flat or cup-style brushes cannot reach. Common applications include weld spatter removal, pipe thread cleaning, casting flash removal, and corrosion cleanup inside bored or threaded passages. The crimped wire construction maintains consistent pressure across irregular surfaces and is appropriate for both ferrous and hard non-ferrous base materials. It is sold individually and is compatible with standard 6 mm collet or chuck setups found on most die grinders and rotary tools.

Installation Notes

Installation is performed by qualified metalworking or maintenance personnel. Before mounting, confirm the tool spindle speed does not exceed the 25,000 RPM rating marked on the brush. Secure the 6 mm shank fully into the collet or chuck and tighten to the tool manufacturer's specified torque before operating. Always wear appropriate eye protection and follow applicable workplace safety standards when operating wire brushes at speed.
