Value Collection 516169 Mounted Polishing Bob Olive Wool Felt

Product Description

The VALUE COLLECTION 516169 is a mounted polishing bob in an olive shape, designed for precision polishing and finishing work on metal, plastic, and similar surfaces. Constructed from hard-density wool felt, this bob delivers consistent surface contact and uniform material removal during rotary tool operations. The 1/8 inch shank diameter fits standard rotary tools, die grinders, and flex-shaft machines. With a maximum diameter of 0.5 inches and a head length of 0.75 inches, it is well suited for detail work in confined areas, internal bores, and contoured surfaces. It is used primarily by machinists, toolmakers, jewelers, and metalworking professionals.

This polishing bob is intended for use with rotary tools and die grinders operating at appropriate RPM ranges for felt polishing media. Its olive shape makes it particularly effective for polishing inside curved recesses, chamfers, and irregular profiles where flat or cylindrical media cannot maintain consistent contact. The 2 inch shank length provides adequate reach for many tooling setups. Suitable for light deburring, surface preparation, and final polish passes on precision components in both shop and field environments.

Installation Notes

Insert the 1/8 inch shank fully into the collet of the rotary tool or die grinder and tighten securely before operation. Ensure the tool is powered off and the collet is fully released before mounting or removing the bob. Select an appropriate spindle speed for wool felt media to avoid overheating the workpiece surface. Eye protection should be worn during all rotary polishing operations.
