Value Collection 516100 Flame Mounted Polishing Bob Wool Felt

Product Description

The VALUE COLLECTION 516100 is a flame-shape mounted polishing bob designed for fine polishing, deburring, and surface finishing on metal, wood, and similar materials. Constructed from hard-density wool felt, this bob delivers consistent cutting and polishing action across a range of applications. It measures 5/16 inches in maximum diameter with a 5/8-inch head length, and mounts on a 3/32-inch diameter shank with a 2-inch shank length for secure chuck engagement. Machinists, toolmakers, and metalworking technicians use this style of mounted bob with rotary tools, die grinders, and flex-shaft machines to reach contoured and tight-access surfaces where flat media cannot conform.

This flame-shape polishing bob is suited for precision surface work in both shop and field settings. The flame geometry allows access to concave profiles, grooves, and recessed areas. Hard-density wool felt provides the firmness needed for controlled stock removal and pre-polish preparation on metals, plastics, and composites. It is a standard toolroom consumable used by machinists, jewelers, mold makers, and finishing technicians who require a consistent, repeatable polishing surface on detailed or contoured workpieces.

Key Features

• Flame shape conforms to concave profiles, grooves, and recessed geometry
• Hard-density wool felt construction for controlled polishing pressure and consistent finish
• 5/16-inch maximum diameter for access to tight and detailed areas
• 3/32-inch shank diameter fits standard rotary tool and die grinder collets
• 2-inch shank length provides reach and stable chuck engagement

Compatibility

Designed for use with rotary tools, die grinders, and flex-shaft machines accepting a 3/32-inch collet or chuck. Suitable as a general-purpose mounted polishing bob for metalworking, toolroom, and finishing applications.

Installation Notes

Install the shank fully into the collet or chuck before tightening to ensure concentricity and reduce runout. Verify the tool's rated RPM is appropriate for the bob diameter before operation. Wear appropriate eye protection when using rotary abrasive or polishing tools. Inspect the felt bob for wear or detachment from the shank before each use and replace if the bond shows signs of degradation.
