Value Collection 516129 Cylinder Polishing Bob Wool Felt

Product Description

The VALUE COLLECTION 516129 is a cylinder-shaped mounted polishing bob designed for precision surface finishing and polishing applications. Constructed from medium-density wool felt, this bob mounts on a 1/4-inch shank and delivers consistent, controlled polishing action on metal, wood, plastic, and similar workpiece materials. The cylinder geometry provides uniform contact along the length of the working surface, making it well suited for polishing flat faces, recessed areas, and cylindrical bores. At 1 inch in maximum diameter and 1 inch in head length, it fits standard die grinders, rotary tools, and drill press setups. Total shank length is 2 inches. The part weighs approximately 0.04 pounds.

This mounted polishing bob is used in metalworking, tool-and-die, jewelry finishing, and general fabrication shops where controlled surface finishing is required. It is appropriate for both bench-mounted rotary tools and handheld die grinders in production or maintenance environments. Machinists, toolmakers, and metal finishers reach for cylinder bobs when they need to work into slots, recesses, or flat faces where wheel-style abrasives cannot reach effectively.

Key Features

• Cylinder shape provides uniform contact on flat faces and recessed surfaces
• Medium-density wool felt construction for controlled polishing without aggressive material removal
• 1/4-inch shank diameter fits standard die grinders and rotary tool collets
• 1-inch maximum diameter and 1-inch head length for precise access in tight areas
• 2-inch shank length for adequate reach and secure tool chuck engagement

Compatibility

Designed as a standard-shank mounted polishing bob compatible with rotary tools, die grinders, and drill presses accepting a 1/4-inch collet or chuck.

Installation Notes

Installation is performed by machinists or metal finishing technicians using a collet or chuck that accepts a 1/4-inch shank. Before mounting, confirm the rotary tool or die grinder is unplugged or powered off and the collet nut is fully released. Insert the shank to the recommended depth and tighten the collet securely before operation. Do not exceed the maximum RPM rating of the tool or the bob material.
