Value Collection 516175 Polishing Bob Ball Wool Felt Hard

Product Description

The VALUE COLLECTION 516175 is a ball-shaped mounted polishing bob designed for precision surface finishing, deburring, and polishing operations on metal, wood, and composite materials. Constructed from hard-density wool felt, it delivers consistent material removal and a fine finish on contoured or flat surfaces. The 1/4-inch shank mounts directly into standard die grinders, rotary tools, and flex-shaft machines. With a maximum diameter of 3/4 inches and a head length of 3/4 inches, this bob suits detail work in tight areas where larger abrasive tools cannot reach. Machinists, toolmakers, and finishing technicians are the primary users in shop and field applications.

This polishing bob is suited for light to medium polishing and blending work on interior cavities, bores, and curved surfaces. Its ball profile makes it well-matched to contoured workpieces, die cavities, mold surfaces, and jewelry finishing. The hard felt density provides firmer contact pressure, making it appropriate for use with polishing compounds to achieve a refined surface finish. Shank length of 2 inches provides reach into recessed areas. Compatible with rotary and die grinding equipment accepting a 1/4-inch shank.

Installation Notes

Installation is performed by machinists, toolmakers, or finishing technicians using standard rotary or die grinder equipment. Secure the 1/4-inch shank fully into the collet or chuck before operation and verify the locking mechanism is tight. Always operate within the speed rating of the tool and wear appropriate eye protection and gloves when using polishing compounds. Inspect the felt bob for wear or separation before each use and replace if the head shows signs of deterioration.
