Value Collection 516152 Conical Polishing Bob Wool Felt

Product Description

The VALUE COLLECTION 516152 is a conical mounted polishing bob made from hard-density wool felt. It is designed for use with rotary tools, die grinders, and bench-mounted polishing equipment. The conical shape concentrates polishing action at a point or along a surface contour, making it effective for finishing work in recesses, cavities, and irregular profiles. The 1/4 inch shank seats directly into standard collets or chuck accessories. At 0.05 pounds, the bob adds minimal rotating mass. Machinists, tool and die workers, and metalworking technicians use this type of bob for final surface finishing and light deburring on metal, wood, and plastic workpieces.

This mounted polishing bob suits bench work and handheld rotary tool applications in machine shops, production finishing lines, and maintenance environments. The conical geometry makes it well suited for finishing inside bores, chamfers, and tapered surfaces where flat or cylindrical media cannot reach. The hard felt density provides firm contact pressure, which supports controlled material removal and consistent surface finish results on harder workpiece materials.

Key Features

Installation Notes

A licensed or qualified machinist or metalworking technician should mount this bob in a compatible rotary tool or die grinder collet. Ensure the tool is powered off and depressurized before inserting or removing the shank. Verify the shank is fully seated and the collet is tightened securely before operating. Do not exceed the maximum RPM rating of the host tool for mounted felt accessories.
