Weiler 86099 End Brush 3/8 in Nylon Crimped 120 Grit

Product Description

The WEILER 86099 is a nylon-fill end brush designed for targeted surface finishing, deburring, and cleaning in hard-to-reach areas. The crimped wire configuration provides consistent pressure across the work surface, while the ceramic abrasive nylon filament at 120 grit delivers controlled material removal without aggressive undercutting. With a 3/8 inch brush diameter and a 10,000 RPM maximum speed rating, this brush is well suited for use with standard die grinders and rotary tools common in production, maintenance, and fabrication environments. The steel shank mounts directly into a standard 1/4 inch collet for secure, low-runout operation.

This end brush is used in applications requiring precise access to recesses, internal features, bores, and tight contours where larger brushes cannot reach. It is appropriate for light deburring, surface prep, blending, and cleaning tasks on metal, composite, and other materials. The crimped nylon construction makes it effective on softer substrates where wire brushes would cause damage. Machinists, maintenance technicians, and fabricators in industrial, aerospace, and general manufacturing settings commonly specify this brush for detail finishing work.

Key Features

• Crimped nylon fill with ceramic abrasive provides controlled 120 grit cutting action
• 3/8 inch brush diameter accesses recesses, internal features, and tight geometry
• Rated to 10,000 RPM for use with standard die grinders and rotary tools
• Steel shank included for direct collet mounting — no adapter required
• Non-bridled, non-encapsulated, non-flared design for open filament contact
• Compact 2-3/8 inch overall length minimizes interference in confined work areas

Compatibility

Designed as a direct-mount end brush for rotary tools and die grinders accepting a 1/4 inch shank, suitable for deburring, blending, and cleaning applications across general industrial and maintenance uses.

Installation Notes

Installation is performed by trades and technicians using standard die grinders or rotary tools with a 1/4 inch collet. Ensure the tool is fully powered down and the collet is securely tightened before operation. Do not exceed the rated 10,000 RPM maximum speed. Wear appropriate eye protection and follow applicable facility safety procedures when operating rotary abrasive tooling.
