Value Collection 516143 Mounted Polishing Bob Oval Wool Felt

Product Description

The VALUE COLLECTION 516143 is a mounted polishing bob designed for fine polishing, buffing, and surface finishing work on metal, wood, and similar materials. Built in an oval shape from rock-hard density wool felt, this bob delivers firm, consistent contact pressure suited to deburring, finish polishing, and detail work in recesses or contoured surfaces. The 1/4-inch shank diameter mounts directly into standard die grinders, rotary tools, and drill press chucks. Maximum bob diameter is 1 inch with a head length of 1 inch and a 2-inch shank length, making it compact and easy to control in tight workspaces.

This polishing bob is used across metalworking, toolmaking, jewelry finishing, and precision machining applications. Its rock-hard felt density makes it appropriate for use with polishing compounds on hardened metals and ferrous surfaces where a softer felt would deflect or wear too quickly. Machinists, toolmakers, and fabricators typically reach for this style of bob when working bore interiors, shaft ends, or small contoured faces that require a mounted abrasive or polishing media on a rotating tool.

Key Features

Compatibility

Designed for use with die grinders, rotary tools, and drill presses accepting a 1/4-inch shank mounted accessory. Compatible with standard polishing compounds applied to the felt surface.

Installation Notes

A licensed machinist or general fabricator typically installs this accessory. Before mounting, ensure the rotary tool or die grinder is powered off and unplugged or air supply is isolated. Insert the 1/4-inch shank fully into the collet and tighten securely before operation. Do not exceed the maximum RPM rating of the tool or apply side loads that could deflect the shank.
