Weiler 90303 End Brush 2-3/4 in Crimped Wire Steel 16000 Rpm

Product Description

The WEILER 90303 is a steel crimped-wire end brush designed for surface preparation, deburring, cleaning, and blending on metal workpieces. It measures 2-3/4 inches in diameter and mounts via a 6 mm shank that is included with the brush. The crimped wire construction provides controlled flexibility, allowing the filament tips to conform to irregular surfaces without aggressive gouging. Rated to a maximum of 16,000 RPM, this brush is suited for use with die grinders, rotary tools, and similar power tools. Wire diameter runs up to 0.0100 inch. It is intended for use by machinists, fabricators, maintenance technicians, and industrial tradespeople who require consistent wire-brush performance at higher rotational speeds.

This end brush is a standard choice for weld cleanup, rust and scale removal, paint stripping, and surface conditioning on ferrous metals. The flared wire configuration increases surface contact at the working face, making it effective on flat surfaces, inside bores, and recessed areas. It is commonly used in metalworking shops, maintenance facilities, and fabrication environments where a rotary-mounted brush tool is needed for localized or spot-cleaning tasks. The included 6 mm shank provides direct compatibility with collet-style tool holders.

Key Features

• 2-3/4 inch brush diameter for broad working contact on flat and recessed surfaces
• Steel crimped wire construction delivers controlled flexibility and durability on ferrous workpieces
• Rated to 16,000 RPM for use with high-speed die grinders and rotary tools
• Wire diameter up to 0.0100 inch provides moderate aggressiveness suited to deburring and cleaning
• Flared wire configuration increases tip contact area at the working face
• 6 mm shank included — mounts directly to standard collet-style tool holders without adapters

Compatibility

Designed as an OEM-style end brush for use with die grinders, rotary tools, and other power tools equipped with a 6 mm collet or compatible chuck. Verify that the tool's rated free speed does not exceed 16,000 RPM before mounting.

Installation Notes

Installation is performed by tradespeople and machinists familiar with rotary abrasive and brush tooling. Before mounting, confirm the host tool's no-load RPM does not exceed the 16,000 RPM maximum rating of this brush. Insert the 6 mm shank fully into the collet and tighten securely before operation. Always wear appropriate eye protection and face shielding when operating wire brush tooling, as wire filaments can break loose during use.
