Value Collection 516108 Cylinder Polishing Bob Wool Felt

Product Description

The VALUE COLLECTION 516108 is a cylinder-shaped mounted polishing bob designed for fine finishing, deburring, and surface polishing tasks on metal, plastic, and similar materials. Constructed from medium-density wool felt, it delivers consistent, controlled polishing action without aggressive material removal. The 0.25-inch maximum diameter and 1/8-inch shank diameter make it well suited for rotary tools, die grinders, and flex-shaft machines. With a 3/8-inch head length and 2-inch shank length, the bob fits securely into standard collet chucks and reaches into recesses, bores, and contoured surfaces that larger abrasive tools cannot access. Machinists, toolmakers, and finishing technicians commonly use this type of bob for final-stage polishing work.

This mounted polishing bob is appropriate for use in machine shops, tool-and-die operations, jewelry finishing, and general metalworking environments. It is suited for light polishing compounds and rouge applications on tight-tolerance surfaces where consistent finish quality is required. The cylinder profile maintains contact along its full length on flat or slightly curved surfaces, making it effective for channel work, keyways, and bore finishing. Sold individually, it is a practical single-piece replacement or addition to a polishing kit.

Key Features

• Cylinder shape maintains full-length surface contact on flat and contoured workpieces
• Medium-density wool felt provides controlled polishing without aggressive stock removal
• 0.25-inch maximum diameter fits into bores, recesses, and tight finishing areas
• 1/8-inch shank diameter is compatible with standard rotary tool and die grinder collets
• 2-inch shank length provides reach for recessed or deep-cavity polishing applications
• 3/8-inch head length delivers adequate polishing surface for small-area finish work

Compatibility

Designed as a standard mounted polishing bob compatible with rotary tools and die grinders accepting a 1/8-inch shank diameter collet.

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. Ensure the tool is powered off and unplugged before inserting or removing the bob. Operate within the speed rating of the tool and avoid excessive lateral force, which can cause the felt head to distort or the shank to deflect. Apply polishing compound directly to the workpiece or bob surface rather than pressing the bob into abrasive media.
