Value Collection 516136 Mounted Polishing Bob Wool Felt

Product Description

The VALUE COLLECTION 516136 is a cylinder-shaped mounted polishing bob designed for surface finishing, deburring, and polishing operations on metal, wood, and similar materials. Constructed from rock-hard density wool felt, this bob delivers consistent pressure and controlled material removal when used with a rotary tool, die grinder, or drill press. The 1/4-inch shank provides a secure chuck connection, while the 1-inch maximum diameter and 1-1/2-inch head length make it well-suited for working in tight contours, bores, and detailed surface areas. Machinists, toolmakers, and finishing technicians are the primary users of this type of accessory.

This mounted polishing bob is used in precision finishing applications where surface consistency matters. The cylinder geometry contacts flat and curved surfaces evenly, making it appropriate for polishing die cavities, mold surfaces, cylindrical bores, and small mechanical components. It is commonly used in machine shops, maintenance environments, and production finishing operations. The rock-hard felt density provides minimal deflection under load, which supports accurate edge work and controlled finishing passes.

Key Features

• Cylinder shape for consistent surface contact on flat and curved workpieces
• Rock-hard wool felt density minimizes deflection during polishing passes
• 1 inch maximum diameter suits tight contours, bores, and detailed geometry
• 1/4 inch shank diameter fits standard die grinder and rotary tool chucks
• 1-1/2 inch head length provides extended reach into recessed areas
• 2 inch shank length allows use in deeper setups and extended reach applications

Compatibility

Designed for use with rotary tools, die grinders, and drill presses accepting a 1/4-inch shank. Compatible with standard collet and chuck configurations commonly found on benchtop and handheld rotary finishing equipment.

Installation Notes

Installation is performed by a machinist or finishing technician. Insert the 1/4-inch shank fully into the tool chuck or collet and tighten securely before operation. Ensure the rotary tool or die grinder is powered off and unplugged before mounting or removing the bob. Do not exceed the recommended RPM rating of the host tool, and inspect the felt bob for wear or separation before each use.
