Weiler 10155 End Brush 1 in Nylon Crimped 320 Grit

Product Description

The WEILER 10155 is a 1-inch diameter end brush fitted with a 6 mm shank and filled with crimped nylon filament loaded with silicon carbide abrasive. Rated to 10,000 RPM, it delivers targeted brushing action inside recesses, bores, and internal features where flat or cup-style brushes cannot reach. The 320-grit extra-fine grade removes light burrs and surface oxides without aggressive material removal. Overall length is 2.75 inches with a 0.75-inch shank, making it compatible with standard die grinders and rotary tools. The shank is included. Machinists, tool-and-die technicians, and maintenance trades use this brush for precision deburring in confined interior geometries.

This end brush is suited for deburring small recessed areas, internal ports, counterbores, and similar tight-access features on metal and composite workpieces. The crimped wire construction provides consistent filament contact pressure throughout the wear life of the brush. At 320 grit with silicon carbide fill, it is well-matched to finish deburring and light surface prep on aluminum, steel, and non-ferrous alloys. Typical use cases include production machining shops, maintenance repair operations, and fabrication environments where precision interior access is required. Package quantity is one brush per unit.

Compatibility

Designed for use with die grinders and rotary tools accepting a 6 mm shank; suitable for deburring and light abrasive finishing in recessed and internal workpiece features across general machining and fabrication applications.

Installation Notes

Installation is performed by tool-and-die technicians or maintenance trades using a die grinder or rotary tool with a compatible 6 mm collet or chuck. Ensure the workpiece and machine are secured before mounting the brush, and confirm the tool's RPM rating does not exceed 10,000 RPM. Wear appropriate eye protection and follow ANSI B11 or shop-specific safe-use guidelines for abrasive accessories. Inspect the brush for filament damage before each use and do not force the brush into a recess smaller than its diameter.
