Value Collection 516112 Mounted Polishing Bob Wool Felt

Product Description

The VALUE COLLECTION 516112 is a cylinder-shaped mounted polishing bob designed for precision surface finishing and polishing applications. Constructed from hard-density wool felt, this bob delivers consistent cutting and polishing action on metals, plastics, and other materials. The 3/8-inch maximum diameter and 1/8-inch shank diameter make it compatible with standard rotary tools, die grinders, and flex-shaft machines. The 2-inch shank length provides secure chuck engagement, and the 3/8-inch head length concentrates polishing action in tight areas or contoured surfaces. It is a single-piece consumable tool used by machinists, tool and die workers, jewelers, and finishing technicians.

This mounted polishing bob is suited for detail work in confined areas where larger buffing wheels cannot reach. Common applications include deburring, blending, and final polishing of bores, slots, cavities, and irregular surfaces. The hard felt density is appropriate for use with polishing compounds to achieve a refined finish on ferrous and non-ferrous metals. It is typically used in machine shops, tool rooms, and finishing departments at both production and job-shop scale.

Key Features

• Cylinder shape concentrates polishing pressure for controlled material contact
• Hard-density wool felt construction supports use with polishing and lapping compounds
• 3/8-inch maximum diameter fits tight bores and confined surface features
• 1/8-inch shank diameter fits standard rotary tool and die grinder collets
• 2-inch shank length provides stable chuck engagement during high-speed operation

Compatibility

Designed for use with rotary tools, die grinders, and flex-shaft machines accepting a 1/8-inch shank collet. Consult tool manufacturer specifications to confirm maximum RPM rating before use.

Installation Notes

Secure the 1/8-inch shank fully into the collet of the rotary tool or die grinder before operation. Ensure the tool is powered off and unplugged before mounting or removing the bob. Do not exceed the maximum RPM rating of either the tool or the bob. Apply polishing compound to the bob or workpiece surface as appropriate for the finishing operation.
