Value Collection 516170 Polishing Bob Olive Wool Felt

Product Description

The VALUE COLLECTION 516170 is a mounted polishing bob in an olive shape, designed for precision surface finishing on metals, plastics, and similar materials. Constructed from rock-hard density wool felt, it delivers consistent cutting and polishing action in tight contours and recessed areas. The 1/8 inch shank 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, this bob is sized for detail work where larger wheels cannot reach. It is commonly used by machinists, toolmakers, jewelers, and finishing technicians.

This polishing bob is suited for bench-top and handheld rotary tool applications in machine shops, manufacturing environments, and metalworking facilities. The olive shape conforms to curved and concave surfaces, making it effective for bore finishing, cavity polishing, and contour work on mold components or precision parts. It mounts directly into a collet or Jacobs-style chuck without additional adapters when using standard 1/8 inch tooling.

Installation Notes

Installation is performed by inserting the 1/8 inch shank into the appropriate collet or chuck and tightening securely before operation. Ensure the rotary tool or grinder is powered off and unplugged before mounting or removing the bob. Do not exceed the maximum RPM rating of the tool being used, and inspect the felt bob for wear or separation before each use. This accessory is typically installed and used by machinists, toolmakers, or finishing technicians familiar with rotary abrasive tooling.
