Value Collection 516173 Polishing Bob Ball Wool Felt

Product Description

The VALUE COLLECTION 516173 is a ball-shape mounted polishing bob designed for precision surface finishing, deburring, and polishing operations on metal, wood, and composite materials. Constructed from rock-hard density wool felt, this bob delivers consistent cutting action and surface refinement in confined areas and contoured surfaces. The 0.5-inch maximum diameter ball head mounts on a 0.125-inch shank, making it compatible with standard rotary tools, die grinders, and flex-shaft machines. Machinists, toolmakers, and finishing technicians reach for this type of accessory when polishing bores, cavities, or detailed workpiece geometry that flat media cannot reach.

This mounted polishing bob is suited for bench-top rotary tool use in machine shops, tool-and-die operations, jewelry finishing, and general metalworking environments. The ball shape provides even contact on curved and radiused surfaces. With a 2-inch shank length and 0.125-inch shank diameter, it seats securely in standard collet chucks and quick-change tool holders found on most die grinders and Dremel-style rotary tools. It is sold individually and is appropriate for both production use and one-off finishing tasks.

Key Features

• Ball-shape head for consistent contact on curved, radiused, and contoured surfaces
• Rock-hard density wool felt construction for aggressive polishing and fine surface refinement
• 0.5-inch maximum diameter fits confined bores, cavities, and detailed geometry
• 2-inch shank length provides reach into deeper workpiece features
• 0.125-inch shank diameter seats in standard collet chucks and die grinder tool holders

Compatibility

Designed for use with standard rotary tools, die grinders, and flex-shaft machines accepting a 0.125-inch shank diameter collet or quick-change holder.

Installation Notes

Install the shank fully into the collet chuck before tightening to the tool manufacturer's specified torque. Ensure the rotary tool or die grinder is disconnected from power before changing accessories. Operate within the maximum RPM rating of the tool; do not exceed the bob's rated speed. Eye protection and appropriate PPE are required during all rotary polishing operations.
