The VALUE COLLECTION 516124 is a cylinder-shaped mounted polishing bob designed for precision surface finishing, deburring, and polishing work on metal, wood, and similar materials. Constructed from hard-density wool felt, this bob delivers consistent surface contact and controlled cut, making it well suited for use with rotary tools, die grinders, and flexible shaft machines. The 1/8-inch shank fits standard collets and chucks found on most bench-top and handheld rotary equipment. With a 3/4-inch maximum diameter and a 3/4-inch head length, this bob targets small-bore and contoured work where precision matters most. Machinists, tool-and-die techs, and finishing specialists are the primary users of this type of accessory.
This mounted polishing bob is used in tool rooms, machine shops, and light fabrication settings for finishing interior bores, slots, and curved profiles. The cylinder shape allows uniform contact along both the face and sides of the bob, making it practical for polishing cylindrical cavities, mold surfaces, and tight recesses. It suits applications where a softer abrasive media is not aggressive enough but where hard felt with polishing compound provides the right surface action. Typical use involves applying a polishing or lapping compound directly to the felt bob before operation.
Designed as an OEM-style replacement or general-use mounted polishing bob compatible with rotary tools, die grinders, and flexible shaft machines accepting a 1/8-inch shank collet.
Installation is performed by trade machinists, finishing technicians, and toolroom professionals. Before mounting, confirm the rotary tool or grinder is powered off and the collet is fully released. Insert the 1/8-inch shank fully into the collet and tighten securely before operation. Apply polishing compound to the felt bob prior to use rather than to the workpiece directly to ensure even distribution and reduce compound waste.
