Value Collection 516157 Oval Wool Felt Polishing Bob

Product Description

The VALUE COLLECTION 516157 is a mounted polishing bob designed for precision surface finishing and polishing work. Constructed from hard-density wool felt, this bob delivers consistent cut and polish on metal, wood, and composite surfaces. The oval bob shape conforms to contoured workpieces and recessed areas where flat or cylindrical tools cannot reach. It mounts on a 1/8 inch shank, making it compatible with standard rotary tools, die grinders, and flex-shaft machines. Machinists, tool and die workers, jewelers, and fabricators use this type of bob for final finishing passes, burr removal, and surface prep prior to coating or inspection.

This polishing bob suits bench-top and handheld rotary tool applications in both shop and field environments. The hard felt density provides enough firmness to maintain shape under pressure while still conforming slightly to workpiece geometry. Typical applications include polishing bores, slots, radii, and contoured surfaces on metal parts. The 1/8 inch shank fits standard collets found on most rotary tools and die grinders used in metalworking and finishing trades.

Installation Notes

Install by inserting the 1/8 inch shank fully into the collet of a compatible rotary tool or die grinder and tighten securely before operation. Ensure the tool is powered off and unplugged before mounting or removing the bob. Inspect the felt bob for wear, fraying, or imbalance before each use and replace if the material shows significant degradation. Always wear appropriate eye protection when operating rotary finishing tools.
