Value Collection 516154 Oval Wool Felt Mounted Polishing Bob

Product Description

The VALUE COLLECTION 516154 is an oval-shaped mounted polishing bob constructed from hard-density wool felt. It mounts on a 0.125-inch shank and reaches a maximum diameter of 0.5 inches, making it well suited for fine polishing, deburring, and surface finishing work in tight or contoured areas. The hard felt density provides firm contact pressure against the workpiece, which helps maintain consistent material removal and surface refinement on metals, plastics, and other materials. This type of mounted bob is commonly used with rotary tools, die grinders, and bench-mounted spindles by machinists, toolmakers, and precision finishing technicians.

This mounted polishing bob is intended for use in precision machining, tool-and-die, jewelry, and general metalworking applications where access to small or recessed surfaces is required. The oval profile allows the bob to reach curved and contoured areas that flat or cylindrical media cannot effectively contact. It is sold individually and is suitable for both production and maintenance finishing tasks where a small-diameter, hard felt abrasive media is specified.

Key Features

• Oval bob shape for effective polishing of contoured and recessed surfaces
• Hard-density wool felt construction provides firm, consistent contact pressure
• 0.5-inch maximum diameter fits small-bore and detail finishing applications
• 0.125-inch shank diameter compatible with standard rotary tool and die grinder collets
• 2-inch shank length provides extended reach into deep cavities or bores
• Sold individually for single-piece replacement or trial use

Compatibility

Designed for use with rotary tools and die grinders accepting a 0.125-inch shank. Verify collet size and maximum RPM rating of the host tool before use.

Installation Notes

Installation is performed by inserting the 0.125-inch shank into the appropriate collet or chuck of the rotary tool or die grinder and tightening securely before operation. Always confirm the tool is powered off and unplugged or the air supply is disconnected before mounting or removing the bob. Do not exceed the maximum RPM rating specified for the tool or the abrasive media. Inspect the felt bob for signs of wear, fraying, or uneven density before each use.
