Value Collection 516165 Polishing Bob Bullet 1 in Wool Felt

Product Description

The VALUE COLLECTION 516165 is a bullet-shaped mounted polishing bob designed for surface finishing, deburring, and detail polishing work on metal, wood, and similar materials. Constructed from medium-density wool felt, it delivers consistent, controlled polishing action without aggressive material removal. The 1/4-inch shank mounts directly into standard die grinders, rotary tools, and flex-shaft machines. With a 1-inch maximum diameter and a 2-inch head length, this bob is well suited for reaching into contoured surfaces, bores, and recessed areas where flat or disc-style abrasives cannot access. Machinists, toolmakers, and finishing technicians commonly use this style of bob for final polishing passes and fine surface preparation.

This mounted polishing bob is used in light industrial, machine shop, and precision finishing environments. It is appropriate for bench-mounted rotary tools and handheld die grinders running at speeds compatible with wool felt media. Typical applications include polishing mold cavities, jewelry, small castings, and tool steel surfaces. The bullet profile makes it particularly effective for internal radii and curved channels where a cylindrical or tapered profile is needed for even contact.

Key Features

• Bullet shape provides access to contoured surfaces, bores, and recessed geometry
• Medium-density wool felt construction for consistent polishing without aggressive cutting
• 1-inch maximum diameter for compact fitment in tight areas
• 1/4-inch shank diameter fits standard die grinders and rotary tool collets
• 2-inch head length and 2-inch shank length for balanced reach and control

Compatibility

Designed for use with die grinders, rotary tools, and flex-shaft machines accepting a 1/4-inch shank. Verify maximum RPM rating of the tool against the recommended operating speed for wool felt media before use.

Installation Notes

Installation is performed by inserting the 1/4-inch shank into a compatible collet or chuck and tightening securely before operation. Disconnect power to the tool and confirm the spindle is fully stopped before mounting or removing the bob. Inspect the felt head for wear, fraying, or imbalance before each use, and replace if the bob shows uneven wear that could cause vibration. Follow the tool manufacturer guidelines for maximum operating speed when using mounted felt accessories.
