Value Collection 516189 Cylinder Wool Felt Polishing Bob 3/4 in

Product Description

The VALUE COLLECTION 516189 is a cylinder-shaped mounted polishing bob made from medium-density wool felt. Designed for use with rotary tools and die grinders, this bob mounts via a 1/4-inch shank and delivers consistent surface contact for polishing, buffing, and finishing operations. The wool felt construction holds compound effectively and conforms slightly to contoured surfaces. With a maximum diameter of 0.75 inches and a head length of 1.5 inches, it suits detail work in tight areas where larger wheels cannot reach. Machinists, tool and die workers, jewelers, and general metalworking professionals use this type of bob for final-stage finishing on metal, plastic, and similar materials.

This mounted polishing bob is suited for bench-top and handheld rotary applications in machine shops, fabrication environments, and maintenance operations. The 1/4-inch shank diameter fits standard collets and chuck accessories on die grinders, Dremel-style rotary tools, and drill press setups. Its cylinder geometry provides even surface contact along the full head length, making it useful for polishing flat faces, bores, and recessed surfaces. Sold individually, it is a practical single-unit replacement or addition to an existing set of mounted points and bobs.

Installation Notes

Installation is performed by inserting the 1/4-inch shank into the collet or chuck of the rotary tool and tightening securely before operation. Ensure the tool is powered off and unplugged before mounting or removing the bob. Apply polishing compound to the felt head rather than the workpiece for best results, and inspect the bob for wear or separation before each use. Follow the rotary tool manufacturer's rated RPM limits for mounted accessories of this diameter.
