Value Collection 516127 Cylinder Wool Felt Mounted Polishing Bob

Product Description

The VALUE COLLECTION 516127 is a cylinder-shaped mounted polishing bob constructed from hard-density wool felt. It is designed for use with rotary tools, die grinders, and similar handheld power tools to perform fine polishing, buffing, and surface finishing on metal, plastic, glass, and other materials. The bob measures 0.75 inches in maximum diameter with a 1-inch head length and mounts via a 0.125-inch diameter shank that is 2 inches long. Its hard felt density makes it well suited for aggressive polishing passes and edge work where a softer bob would deflect. Machinists, toolmakers, jewelers, and fabricators reach for this type of bob when a consistent, controlled polishing surface is needed in confined or contoured areas.

This mounted polishing bob is used across a range of finishing applications in machine shops, fabrication facilities, jewelry studios, and maintenance environments. It fits standard rotary tool collets and die grinder chucks that accept a 0.125-inch shank. Typical applications include deburring, oxide removal, light scratch removal, and final-stage polishing on small workpieces or hard-to-reach surfaces. Its cylinder shape delivers uniform contact along its full working face, making it a practical choice for flat surfaces, slots, and inside corners.

Installation Notes

Installation is performed by inserting the shank into the collet or chuck of the rotary tool or die grinder and tightening securely before operation. Ensure the tool is powered off and unplugged or the battery removed before mounting or removing the bob. Verify that the tool's rated RPM is appropriate for the bob diameter to avoid excessive wear or bob failure. Eye protection and appropriate work-holding practices should be observed during all polishing operations.
