Weiler 90299 End Brush 1 in Crimped Steel Wire 22000 Rpm

Product Description

The WEILER 90299 is a crimped steel wire end brush designed for use with rotary tools, die grinders, and power drills. The 1-inch brush diameter and 6 mm steel shank make it a compact tool for cleaning, deburring, blending, and surface preparation in confined areas and hard-to-reach spots. Wire diameter falls in the 0.0101 to 0.0200 inch range, providing moderate aggressiveness for general-purpose metalworking tasks. The brush is rated for a maximum speed of 22,000 RPM, making it compatible with high-speed pneumatic and electric die grinders commonly used in fabrication, maintenance, and industrial service work.

This end brush is suited for both shop and field applications where surface finishing, rust removal, weld cleanup, or burr removal is required on ferrous metals. The crimped wire construction flexes slightly on contact, which helps maintain consistent brush-to-surface contact on irregular or curved surfaces. It is commonly used by machinists, welders, pipefitters, and general maintenance technicians working on steel components, pipe ends, valve bodies, and structural fabrications.

Compatibility

Designed for use with die grinders, flexible shaft tools, and power drills equipped with a 6 mm collet or equivalent chuck. Suitable for general metalworking and surface preparation applications on steel and ferrous materials.

Installation Notes

Always confirm the tool spindle speed does not exceed the 22,000 RPM maximum rating of this brush before operation. Secure the 6 mm shank fully in the collet or chuck before starting the tool. Wear appropriate eye protection and a face shield when operating wire brushes at high speed. Inspect the brush for splayed or broken wires before each use and replace if wire integrity is compromised.
