Value Collection 516144 Conical Wool Felt Polishing Bob

Product Description

The VALUE COLLECTION 516144 is a conical mounted polishing bob made from medium-density wool felt, designed for use in precision polishing, deburring, and surface finishing applications. The bob measures 0.5 inches in maximum diameter with a 1-inch head length, and mounts on a 0.125-inch diameter shank that is 2 inches long, making it compatible with standard rotary tools, die grinders, and bench-mounted flex-shaft machines. The wool felt construction allows the bob to hold and distribute polishing compounds evenly across contoured or recessed surfaces. Machinists, toolmakers, and finishing technicians typically use this type of bob for fine work on metals, plastics, and composite materials.

This polishing bob is suited for light to medium finishing tasks where a controlled, consistent surface contact is needed. The conical shape makes it well-suited for working inside bores, cavities, and angled recesses where flat or cylindrical abrasives cannot reach. It is commonly used in machine shops, jewelry finishing, and general fabrication settings. The 0.125-inch shank fits collets and chuck adapters standard across most hand-held and bench rotary tool setups.

Key Features

• Conical shape for access to recessed surfaces, bores, and angled cavities
• Medium-density wool felt construction holds polishing compound effectively

Compatibility

Designed for use with rotary tools, die grinders, and flex-shaft machines accepting a 0.125-inch shank diameter.

Installation Notes

Installation is performed by inserting the shank into the collet or chuck of the rotary tool and tightening securely before operation. Ensure the tool is powered off and unplugged before mounting or removing the bob. Apply polishing compound directly to the felt surface prior to use, and operate at speeds appropriate for wool felt media to avoid overheating or deformation of the bob.
