Value Collection 516188 Mounted Polishing Bob Cylinder Wool Felt

Product Description

The VALUE COLLECTION 516188 is a cylinder-shaped mounted polishing bob designed for precision polishing, deburring, and surface finishing work on metals, plastics, and other materials. Constructed from rock hard density wool felt, this bob delivers consistent pressure and a smooth finish when driven by a rotary tool or die grinder. The 0.125 inch shank fits standard collets on most rotary tools, while the 0.5 inch maximum diameter and 0.75 inch head length make it well suited for detail work in confined areas. It is commonly used by machinists, jewelers, toolmakers, and finishing technicians.

This mounted polishing bob is appropriate for bench-top and handheld rotary tool applications in manufacturing, maintenance, and finishing environments. The cylinder geometry allows uniform contact along the side of the bob, making it effective for polishing the interior walls of bores, slots, and channels as well as flat surfaces. The rock hard felt density holds its shape under load and provides controlled, repeatable results on fine surface finishing tasks. It is sold individually and is ready to mount directly into a compatible collet.
