Value Collection 516186 Mounted Polishing Bob Wool Felt

Product Description

The VALUE COLLECTION 516186 is a cylinder-shaped mounted polishing bob designed for fine polishing, deburring, and surface finishing work on metals, plastics, and similar materials. Constructed from medium-density wool felt, the bob measures 0.5 inches in maximum diameter with a 0.75 inch head length. It mounts via a 0.125 inch shank, making it compatible with standard rotary tools, die grinders, and flex shafts. Machinists, toolmakers, and finishing technicians use this style of bob for detail work in confined areas where flat or large-format polishing wheels cannot reach. The wool felt material holds polishing compound well and delivers a consistent finish.

This mounted polishing bob is suited for bench-top and handheld rotary tool applications in machine shops, tool rooms, and fabrication environments. It is commonly used for internal bore polishing, cavity finishing in molds and dies, and touch-up work on contoured surfaces. The cylinder profile provides even contact across flat and slightly curved interior surfaces. The 2 inch shank length allows reach into deeper cavities without interference from the tool chuck.

Key Features

• Cylinder shape provides consistent surface contact for flat and interior finishing applications
• Medium-density wool felt holds polishing compound effectively for controlled material removal
• 0.5 inch maximum diameter suits tight-clearance and small-bore work
• 0.125 inch shank diameter fits standard rotary tool and die grinder collets
• 2 inch shank length allows reach into recessed cavities and deep features
• Lightweight at under 0.01 pounds, minimizing load on handheld tools

Compatibility

Designed for use with rotary tools, die grinders, and flex shaft machines accepting a 0.125 inch shank. Confirm collet size on the host tool before mounting.

Installation Notes

Installation is performed by inserting the 0.125 inch shank into the appropriate collet on the rotary tool or die grinder and tightening securely per the tool manufacturer's instructions. Ensure the tool is powered off and unplugged before mounting or removing the bob. Inspect the felt head for damage or loose material before use, and do not exceed the maximum RPM rating of the host tool. Apply polishing compound to the bob rather than directly to the workpiece for best results.
