Value Collection 516149 Conical Polishing Bob Wool Felt

Product Description

The VALUE COLLECTION 516149 is a conical mounted polishing bob designed for precision polishing, buffing, and finishing work on metal, wood, and composite surfaces. Constructed from rock-hard density wool felt, this bob delivers consistent pressure and uniform contact across the work surface. The 3/4 inch maximum diameter conical head mounts on a 1/4 inch shank, making it compatible with standard rotary tools, die grinders, and drill presses. Machinists, toolmakers, jewelers, and metalworking technicians use this type of bob for fine surface finishing, cavity polishing, and deburring in tight or contoured areas.

This mounted polishing bob is suited for applications where a rigid, consistent abrasive surface is needed in confined spaces or complex geometries. The conical shape allows access to angled recesses, mold cavities, and contoured workpieces that flat or cylindrical bobs cannot reach effectively. It is commonly used in machine shops, tool and die operations, jewelry finishing, and precision metalworking environments. The 1.5 inch head length and 2 inch shank length provide adequate reach for most benchtop and handheld rotary tool setups.
