Value Collection 516107 Mounted Polishing Bob Wool Felt

Product Description

The VALUE COLLECTION 516107 is a cylinder-shaped mounted polishing bob designed for fine polishing, deburring, and surface finishing work on metal, stone, and similar materials. Constructed from rock hard density wool felt, this bob delivers consistent, controlled contact pressure during rotary tool operation. The 1/4 inch maximum diameter and 1/8 inch shank diameter make it compatible with standard die grinders, rotary tools, and flex shafts. With a head length of 1/4 inch and a shank length of 2 inches, it provides adequate reach for recesses, cavities, and tight workpiece geometry.

This mounted polishing bob is suited for bench-mounted or handheld rotary tool use in machine shops, metal fabrication, jewelry finishing, mold and die work, and precision surface prep applications. The cylinder shape allows edge and bore work where flat or tapered profiles would not seat properly. Machinists, toolmakers, and finishing technicians typically select this bob for final-stage polishing passes where surface quality is critical.

Installation Notes

Installation is performed by inserting the 1/8 inch shank into the collet of a compatible rotary tool or die grinder and tightening securely before operation.

Match the rotary tool speed to the polishing compound and workpiece material — do not exceed the tool manufacturer's recommended RPM for accessories of this shank diameter. Wear appropriate eye protection during use.
