Value Collection 516145 Conical Polishing Bob Wool Felt

Product Description

The VALUE COLLECTION 516145 is a conical mounted polishing bob designed for fine surface finishing and polishing work on metal, wood, and similar materials. Built from hard-density wool felt, this bob delivers consistent cutting and polishing action when used with polishing compounds. It mounts via a 0.125-inch diameter shank, making it compatible with standard rotary tools, die grinders, and drill chucks. The conical shape allows access to contoured surfaces, recesses, and tight profiles where flat or cylindrical bobs cannot reach. At 0.5 inches maximum diameter and 1 inch of head length, it is sized for precision detail work rather than bulk stock removal.

This mounted bob is suited for tool-and-die work, jewelry finishing, mold polishing, and general metalworking applications. It is commonly used in machine shops, fabrication environments, and maintenance settings where a fine, controlled polish is required on small or intricate part features. The wool felt construction holds polishing compound well, making it effective for final-stage finishing passes. Installation and use require no specialized tooling beyond a compatible rotary or pneumatic hand tool with a collet or chuck accepting a 0.125-inch shank.

Installation Notes

A licensed machinist or skilled tradesperson should ensure the rotary tool or grinder is fully powered down and the collet is released before installing or removing the bob. Insert the shank fully into the collet and tighten securely before operation to prevent slippage. Always verify the tool RPM rating does not exceed the rated speed of the bob, and wear appropriate eye protection during use.
