Value Collection 516183 Polishing Bob Cylinder Wool Felt

Product Description

The Value Collection 516183 is a cylinder-shaped mounted polishing bob designed for precision polishing, deburring, and surface finishing tasks. Constructed from medium-density wool felt, this bob delivers consistent surface contact and controlled material removal on metal, plastic, and composite workpieces. The 0.25-inch shank mounts directly into standard die grinders, rotary tools, and drill chucks, making it a practical tool for machinists, tool-and-die technicians, and metal fabricators working in shop or field environments. With a maximum diameter of 1.5 inches and a head length of 1 inch, this bob suits detailed finishing work in confined areas or on curved surfaces.

This mounted polishing bob is suited for use in machine shops, fabrication facilities, and maintenance environments where fine surface finishing or light blending is required. It performs well on interior bores, contoured surfaces, and tight-geometry components. The cylinder profile provides uniform contact along flat and gently curved surfaces, making it appropriate for final polishing stages or preparation work ahead of plating, coating, or inspection. It is typically used by machinists, tool grinders, and precision metalworkers.

Key Features

• Cylinder shape provides uniform contact on flat and curved surfaces
• Medium-density wool felt material for controlled, consistent polishing action
• 1.5-inch maximum diameter suits a range of workpiece geometries
• 0.25-inch shank diameter fits standard rotary tools and die grinders
• 1-inch head length and 2-inch shank length for good reach and stability
• Lightweight construction at approximately 0.008 pounds

Compatibility

Designed for use with standard 0.25-inch collet or chuck rotary tools, die grinders, and drill press setups commonly used in precision metalworking and finishing applications.

Installation Notes

A licensed or experienced machinist or fabricator should mount this bob using the appropriate collet or chuck that matches the 0.25-inch shank diameter. Ensure the rotary tool or die grinder is fully powered off and unplugged before inserting or removing the shank. Verify that the collet is tightened securely before operation to prevent slippage. Always operate within the RPM rating of the host tool and wear appropriate eye protection during use.
