Value Collection 516153 Oval Wool Felt Polishing Bob 0.5 in

Product Description

The VALUE COLLECTION 516153 is a mounted polishing bob designed for fine finishing, buffing, and polishing work on metal, wood, plastic, and similar surfaces. The oval-shaped head is constructed from medium-density wool felt, which provides consistent contact pressure and controlled material removal during polishing operations. The 1/8-inch shank mounts directly into a rotary tool, die grinder, or drill press collet, making it a common choice for machinists, jewelers, tool-and-die workers, and maintenance technicians who need a compact, controllable polishing tip for detailed or contoured work.

This polishing bob is suited for precision surface finishing in shop and field environments. Its oval head geometry allows access to curved surfaces, recesses, and contoured profiles where flat or cylindrical bobs cannot maintain full contact. The medium-density wool felt construction balances cutting action with surface conformity, making it appropriate for intermediate to final polishing stages on ferrous and non-ferrous metals, as well as softer materials. It is typically used with polishing compounds applied directly to the felt head.

Compatibility

Designed as a standard mounted polishing bob for use with rotary tools and die grinders that accept a 1/8-inch shank diameter.

Installation Notes

Mounting is performed by a machinist or technician using the appropriate collet or chuck sized for a 1/8-inch shank. Ensure the rotary tool or grinder is fully powered down and unplugged before inserting or removing the bob. Tighten the collet securely to prevent runout or wobble during operation. Apply polishing compound to the felt head before use and inspect the felt for wear or contamination between polishing sessions.
