Value Collection 516113 Mounted Polishing Bob Cylinder Wool Felt

Product Description

The VALUE COLLECTION 516113 is a cylinder-shaped mounted polishing bob made from rock hard density wool felt. It is designed for use with rotary tools, die grinders, and similar small power tools where fine polishing, buffing, or surface finishing is required. The bob features a 1/8 inch shank diameter for compatibility with standard collet sizes and a maximum working diameter of 3/8 inch. At 3/8 inch head length, it fits into tight spaces and contoured surfaces that larger polishing media cannot reach. Machinists, toolmakers, jewelers, and finishing technicians are the typical users who specify this type of mounted point for detail work.

This mounted polishing bob is suited for bench work and light production finishing on metal, plastic, stone, and similar hard materials. The cylinder shape provides consistent surface contact along its length, making it effective for polishing bores, grooves, slots, and flat faces. The rock hard felt density delivers firm, controlled cut compared to softer felt grades, which allows it to hold compound and maintain shape during repeated use. It is sold and packaged as a single unit.

Key Features

• Cylinder bob shape for consistent contact on flat and contoured surfaces
• Rock hard wool felt density holds polishing compound and resists deformation
• 3/8 inch maximum diameter fits bores, grooves, and confined areas
• 1/8 inch shank diameter fits standard rotary tool and die grinder collets
• 2 inch shank length provides reach into recessed work areas

Compatibility

Designed for use with rotary tools, die grinders, and flex-shaft machines accepting a 1/8 inch collet or chuck.

Installation Notes

Secure the 1/8 inch shank firmly in the tool collet before operation and verify the collet nut is fully tightened. Inspect the felt bob for cracks or loosening at the shank before each use and replace if the bond is compromised. Operate within the maximum RPM rating of the tool and avoid excessive lateral pressure, which can deflect or dislodge the bob. Apply polishing compound to the bob surface before contact with the workpiece rather than directly to the part.
