Value Collection 516192 Cone Polishing Bob Wool Felt

Product Description

The VALUE COLLECTION 516192 is a cone-shaped mounted polishing bob designed for precision surface finishing and polishing work on metal, wood, and similar materials. Constructed from medium-density wool felt, this bob delivers consistent polishing action and conforms to contoured surfaces. The 0.5 inch maximum diameter cone head and 0.125 inch shank diameter make it compatible with standard rotary tools, die grinders, and flex-shaft machines. The 0.75 inch head length and 2 inch shank length provide adequate reach into recesses and tight geometries. Machinists, toolmakers, and finishing technicians use this type of bob for final polishing stages where surface finish quality is critical.

This mounted polishing bob is suited for bench-top rotary tool use in machine shops, metalworking facilities, fabrication shops, and tool-and-die applications. The cone geometry allows access to angled surfaces, chamfers, and inside contours that flat or cylindrical bobs cannot reach effectively. It is typically used with polishing compound applied directly to the felt surface for fine finishing passes on precision parts.

Key Features

• Cone shape provides access to recesses, chamfers, and contoured surfaces
• Medium-density wool felt delivers consistent polishing without aggressive material removal
• 0.125 inch shank diameter fits standard rotary tool and die grinder collets
• 0.75 inch head length suited for moderate-depth reach applications
• 2 inch shank length provides clearance in confined workholding setups
• Lightweight at under 0.01 pounds — minimal added load on spindle bearings

Compatibility

Designed for use with rotary tools, die grinders, and flex-shaft machines accepting a 0.125 inch shank. Suitable as a standard mounted polishing bob replacement in metalworking and finishing applications.

Installation Notes

Power down and disconnect the rotary tool or grinder before inserting or removing the shank from the collet. Tighten the collet securely to prevent slippage at operating speed. Apply polishing compound to the felt bob before contact with the workpiece rather than directly to the part surface. Inspect the bob for wear, unraveling felt, or shank runout before each use and replace if any defects are present.
