Value Collection 516190 Oval Wool Felt Polishing Bob 3/8 in

Product Description

The VALUE COLLECTION 516190 is a mounted polishing bob designed for fine polishing, buffing, and finishing work on metal, wood, and similar surfaces. Built with medium-density wool felt, this oval-shaped bob delivers consistent surface contact and controlled material removal. The 1/8 inch shank fits standard rotary tools, die grinders, and flex-shaft machines. With a maximum diameter of 3/8 inch and a head length of 1/2 inch, this bob is suited for detail work in confined areas, bores, cavities, and contoured surfaces where larger wheels cannot reach. Machinists, tool and die workers, jewelers, and finishing tradespeople use this style of bob for final-stage polishing operations.

This mounted polishing bob is well suited for bench work and machine-side finishing tasks in shops handling precision components, mold cavities, jewelry, and small fabricated parts. The oval profile allows the bob to follow curved and irregular geometries with consistent felt contact. It mounts directly in any rotary tool or handpiece with a standard 1/8 inch collet, making it a practical addition to a general finishing kit. The 2 inch shank length provides adequate reach into recessed areas without requiring an extension.

Installation Notes

Install the shank fully into the collet of the rotary tool or handpiece and tighten the collet securely before operation. Inspect the bob for wear or uneven density before each use and replace if the felt shows significant flattening or contamination. Operate at speeds appropriate for felt polishing bobs as specified by the tool manufacturer. Use appropriate eye protection and secure the workpiece before applying the rotating bob.
