Value Collection 516150 Conical Polishing Bob Wool Felt

Product Description

The VALUE COLLECTION 516150 is a conical mounted polishing bob designed for precision polishing, buffing, and finishing work on metal, wood, plastic, and composite surfaces. Constructed from rock-hard density wool felt, this bob delivers consistent, controlled polishing pressure on contoured and detailed workpiece surfaces. The conical shape allows access to recesses, chamfers, and curved profiles that flat or cylindrical bobs cannot reach. With a 1/4-inch shank diameter, it mounts directly into standard die grinders, Dremel-style rotary tools, and drill chucks. Machinists, toolmakers, jewelers, and finishing technicians use this style of mounted bob for final-stage surface work.

This mounted polishing bob is suited for use in machine shops, tool and die operations, jewelry finishing, and general metalworking environments. The rock-hard felt density makes it appropriate for compound-loaded polishing passes where the bob must hold its shape under lateral pressure. It is sold individually and is well-suited for bench-mounted rotary tools as well as handheld die grinders used in production and prototype finishing applications.

Key Features

• Conical shape provides access to contoured surfaces, recesses, and complex profiles
• Rock-hard wool felt density maintains form under polishing compound pressure

Compatibility

Designed for use with standard rotary tools, die grinders, and drill chucks accepting a 1/4-inch shank. Suitable as a replacement or consumable polishing bob in bench and handheld finishing setups where conical wool felt bobs are specified.

Installation Notes

Installation is performed by inserting the 1/4-inch shank into the collet or chuck of a compatible rotary tool or die grinder and tightening securely before operation. Ensure the tool is powered off and unplugged or the air supply is disconnected before mounting or removing the bob. Verify the tool RPM rating does not exceed the rated speed for wool felt bobs before use. Apply polishing compound to the bob face rather than directly to the workpiece for best results.
