Weiler 90301 End Brush 3/4 in Stainless Steel Crimped Wire

Product Description

The WEILER 90301 is a stainless steel crimped wire end brush designed for surface preparation, deburring, cleaning, and blending on metal workpieces. The brush features a 3/4 inch working diameter and mounts via a 6 mm steel shank, making it compatible with rotary tools, die grinders, and drill presses. Wire diameter falls in the 0.0101 to 0.0200 inch range, delivering moderate aggressiveness suited for general-purpose finishing work. Maximum rated speed is 22,000 RPM. Fabricators, maintenance technicians, pipefitters, and industrial service pros reach for this style of brush when working in tight bores, ports, or recessed surfaces where a wheel brush cannot reach.

The WEILER 90301 is well suited for weld cleaning, rust and scale removal, and surface conditioning in confined areas. It performs on ferrous and non-ferrous metals and is a common choice in pipe fabrication shops, mechanical rooms, and field service applications where portability and tool versatility matter. The stainless steel fill resists contamination of workpiece surfaces where iron transfer from carbon steel wire would be unacceptable, such as in stainless or aluminum finishing work.

Key Features

• 3/4 inch brush diameter for access in bores and recessed areas
• Stainless steel crimped wire fill resists contamination on sensitive base metals
• Wire diameter range 0.0101 to 0.0200 inches for moderate cutting action
• 6 mm steel shank included — mounts directly to die grinders and rotary tools
• 22,000 RPM maximum rated speed
• Not bridled, flared, or encapsulated — straightforward open-face construction

Compatibility

Designed for use with die grinders, drill presses, and rotary tools accepting a 6 mm shank. Verify that the tool spindle speed does not exceed the 22,000 RPM rating of this brush before use.

Installation Notes

Installation is performed by trades and technicians using standard rotary power tools. Ensure the tool is powered off and unplugged before securing the shank in the collet or chuck. Always confirm the tool operating speed does not exceed the brush maximum RPM rating, and wear appropriate eye and face protection during operation. Do not use a brush that shows signs of wire fatigue, uneven wear, or mechanical damage.
