Value Collection 516141 Oval Wool Felt Polishing Bob 1 in

Product Description

The VALUE COLLECTION 516141 is an oval-shaped mounted polishing bob made from medium-density wool felt. Designed for use with rotary tools and die grinders, this bob mounts via a 1/4-inch shank and delivers consistent surface contact for polishing, buffing, and finishing operations on metal, wood, plastic, and composite materials. The oval profile allows access to contoured surfaces and recessed areas where flat or cylindrical bobs cannot reach effectively. At 1 inch maximum diameter and 1 inch head length, it suits detail work requiring controlled material removal and surface refinement. Installed by machinists, toolmakers, and fabricators, it is a standard consumable in bench finishing and hand-tool polishing setups.

This mounted polishing bob is suited for light to medium finishing tasks in shop environments. It works with standard rotary tools, flexible-shaft machines, and pneumatic or electric die grinders fitted with a 1/4-inch collet. Typical applications include deburring, surface blending, pre-plate polishing, and final finishing passes on machined components or castings. The wool felt construction holds polishing compounds well, making it effective for achieving consistent surface finishes across a range of substrate hardnesses.

Compatibility

Designed for use with rotary tools, die grinders, and flexible-shaft machines equipped with a 1/4-inch collet. Suitable as a standard mounted polishing bob replacement in general shop finishing applications.

Installation Notes

Installation requires a rotary tool or die grinder with a matching 1/4-inch collet; ensure the collet is fully tightened before operation. Inspect the bob for wear or separation from the shank before each use and replace if the felt shows signs of deterioration. Apply polishing compound to the bob face rather than the workpiece for best results. Operate at speeds appropriate for wool felt bobs as specified by the tool manufacturer to avoid premature wear or shank runout.
