Value Collection 516115 Polishing Bob Cylinder Wool Felt

Product Description

The VALUE COLLECTION 516115 is a cylinder-shaped mounted polishing bob made from hard-density wool felt, designed for fine polishing and finishing work on metal, wood, plastic, and similar surfaces. The bob measures 0.375 inches in maximum diameter with a 0.5-inch head length, and mounts on a 0.125-inch diameter shank that extends 2 inches for secure chuck engagement. Hard wool felt holds its shape under pressure, making it well suited for consistent surface contact on contoured or flat workpiece geometry. Machinists, tool-and-die workers, jewelers, and finishing technicians use this style of bob with rotary tools, die grinders, and drill presses for light-material removal and final-stage polishing passes.

This mounted polishing bob is appropriate for bench-top and handheld rotary tool applications where a small-diameter, precision polishing tip is required. The cylinder profile delivers uniform surface contact along its full head length, making it effective in recesses, bores, slots, and flat surfaces alike. It is sold individually, making it a practical single-replacement option or a supplement to an existing polishing kit.

Installation Notes

Installation is performed by any machinist, jeweler, or finishing technician familiar with rotary tool operation. Power down and unplug or disconnect the rotary tool before inserting or removing the mounted bob. Seat the shank fully into the collet or chuck and tighten securely before operating. Inspect the wool felt head for wear or separation before each use and replace if the bob shows signs of degradation.
