Weiler 10152 End Brush 3/4 in Nylon Crimped Wire 320 Grit

Product Description

The WEILER 10152 is a nylon-fill end brush designed for targeted deburring and surface finishing in small recessed areas, internal features, and tight geometries. The brush uses crimped nylon filaments loaded with silicon carbide abrasive at 320 grit, rated extra fine, to deliver controlled material removal without aggressive cutting. The 6 mm shank mounts directly in a drill, die grinder, or rotary tool and is rated to a maximum of 10,000 RPM. Overall length is 1.5 inches with a shank length of 0.75 inches. Licensed tradespeople and machinists use this brush when standard tooling cannot reach confined internal surfaces.

This end brush is suited for deburring bores, ports, counterbores, and internal cavities on metal, plastic, or composite workpieces. The crimped filament construction allows the tips to conform to irregular surfaces while maintaining consistent abrasive contact. It is commonly used in HVAC component fabrication, plumbing fitting finishing, and general metalworking where surface prep in recessed areas is required. The extra fine 320-grit silicon carbide abrasive makes it appropriate for light deburring and blending rather than heavy stock removal.

Key Features

• Crimped nylon filaments with silicon carbide abrasive for flexible, consistent contact in recesses
• 320 grit, extra fine grade — suited for light deburring and surface blending
• 6 mm shank diameter, 0.75-inch shank length, fits standard rotary and die grinder chucks
• 10,000 RPM maximum speed rating
• 1.5-inch overall length for access to small internal features and recessed areas
• Not bridled, flared, or encapsulated — standard open-fill construction

Compatibility

Designed for use in rotary tools, die grinders, and drill presses or hand drills accepting a 6 mm shank. Intended for deburring small recessed areas and internal features in general metalworking and fabrication applications.

Installation Notes

Installed by machinists, fabricators, or trade technicians using a compatible rotary tool or die grinder with a 6 mm collet or chuck. Secure the shank fully in the collet before operation and confirm the tool RPM does not exceed the 10,000 RPM maximum rating of this brush. Wear appropriate eye protection and follow shop safety procedures when operating rotary abrasive tools. Inspect the brush for filament damage or wear before each use and replace if filaments are broken or excessively worn.
