The VALUE COLLECTION 516151 is a conical mounted polishing bob designed for surface finishing, deburring, and polishing tasks on metal, wood, and similar materials. Constructed from medium-density wool felt, it delivers consistent cut and polish action suited to contoured and flat surfaces alike. The bob mounts on a 1/4 inch shank, making it compatible with standard rotary tools, die grinders, and drill presses. With a maximum diameter of 1 inch and a head length of 2 inches, it reaches into recessed areas and tight geometry where larger abrasive tools cannot. Machinists, toolmakers, and finishing technicians are the primary installers and operators of this accessory.
This mounted polishing bob is used in shop and field finishing operations where a controlled, consistent polish is required. Its conical shape makes it well suited for internal chamfers, valve seats, mold cavities, and similar contoured surfaces. The medium-density wool felt construction holds compounds effectively, making it a practical choice for buffing compounds and polishing pastes applied during final finishing stages. It is sold individually and is appropriate for both bench and handheld rotary tool setups.
Designed as a standard replacement or consumable polishing bob for rotary tools and die grinders accepting a 1/4 inch shank accessory.
Installation is performed by machinists or finishing technicians using standard rotary tool chuck or collet systems. Ensure the rotary tool or grinder is powered off and unplugged before mounting or removing the bob. Tighten the shank securely in the collet or chuck before operation to prevent slippage at speed. Follow the tool manufacturer's recommended RPM range for felt polishing accessories to avoid overheating the felt or workpiece surface.
