Value Collection 516176 Polishing Bob Ball Wool Felt

Product Description

The VALUE COLLECTION 516176 is a ball-shaped mounted polishing bob designed for precision polishing, deburring, and surface finishing on metal, wood, and similar materials. Constructed from rock hard density wool felt, it delivers consistent pressure and controlled material removal in confined areas and contoured surfaces. The 1/4-inch shank makes it compatible with standard die grinders, rotary tools, and flex shafts. With a maximum diameter of 3/4 inches and a head length of 3/4 inches, this bob is suited for detail work where larger abrasive tools cannot reach. Machinists, tool and die workers, and metal fabricators typically use this type of accessory during final finishing operations.

This polishing bob is well suited for small-shop and production environments where consistent surface finishing is required on tight radii, bores, and irregular profiles. The ball shape allows the tool to conform to concave and convex surfaces alike, making it useful on mold cavities, jewelry components, and precision-machined parts. The 2-inch shank length provides adequate reach into recessed areas without requiring an extension. It is sold individually and intended for single-use or light recurring polishing cycles depending on application intensity.

Compatibility

Designed as an OEM-style replacement or standard accessory for rotary tools, die grinders, and flex-shaft machines accepting a 1/4-inch shank mounted bob.

Installation Notes

Installation requires inserting the 1/4-inch shank into the collet of a compatible rotary or die grinder and tightening securely before operation. Ensure the tool is powered off and disconnected from the power source before mounting or removing the bob. Operate within the RPM rating of the tool and inspect the felt bob for wear or separation before each use. This accessory is typically installed and serviced by machinists, tool grinders, or metal finishing technicians.
