Value Collection 516116 Polishing Bob Cylinder Wool Felt

Product Description

The VALUE COLLECTION 516116 is a cylinder-shaped mounted polishing bob made from rock hard density wool felt. It is designed for fine polishing, deburring, and surface finishing applications on metal, plastic, and similar workpiece materials. The bob measures 0.375 inches in maximum diameter with a 0.5-inch head length and mounts on a 0.125-inch diameter shank that extends 2 inches for use in rotary tools, die grinders, and flexible shaft machines. The rock hard felt density provides firm, consistent contact pressure during polishing passes, making it well suited for reaching recessed areas, bores, and contoured surfaces that flat media cannot access.

This mounted bob is used in toolroom, production, and maintenance settings where controlled polishing action is needed on small or tight-geometry features. Typical applications include polishing mold cavities, jewelry, instrument components, and precision machined parts. It is installed and operated by machinists, tool and die makers, jewelers, and maintenance technicians working with handheld rotary tools or bench-mounted flexible shaft units. The 0.125-inch shank diameter is a common standard size compatible with a wide range of collet-equipped rotary tools.

Key Features

• Cylinder shape provides uniform contact across the full head length for consistent polishing results
• Rock hard wool felt density delivers firm, controlled pressure suitable for final polishing and light material removal
• 0.375-inch maximum diameter and 0.5-inch head length suit small-bore and tight-access polishing tasks
• 0.125-inch shank diameter fits standard collet sizes on most rotary tools and die grinders
• 2-inch shank length provides extended reach into deep cavities or recessed features
• Wool felt construction holds and releases polishing compounds evenly across the work surface

Compatibility

Designed as a standard-shank mounted polishing bob compatible with rotary tools, die grinders, and flexible shaft machines equipped with a 0.125-inch collet or chuck.

Installation Notes

Installation is performed by inserting the 0.125-inch shank into the appropriate collet or chuck and tightening securely before operation. Ensure the tool is powered off and unplugged or the air supply is disconnected before changing accessories. Do not exceed the maximum RPM rating of the rotary tool being used, and inspect the bob for wear or deterioration before each use. Apply polishing compound to the felt bob rather than directly to the workpiece for best results.
