Value Collection 516111 Cylinder Mounted Polishing Bob

Product Description

The VALUE COLLECTION 516111 is a cylinder-shaped mounted polishing bob constructed from medium-density wool felt. It mounts on a 1/8-inch shank and delivers consistent surface contact during polishing and finishing operations. With a maximum diameter of 3/8 inches and a head length of 3/8 inches, it fits into tight contours and small bores where flat or loose abrasives cannot reach. The 2-inch shank length provides adequate clearance from the collet to the workpiece. This bob is used with rotary tools, die grinders, or flexible shaft machines. Machinists, toolmakers, jewelers, and maintenance technicians typically select this style for detail polishing on metal, plastic, and composite surfaces.

The 516111 suits bench-top and handheld rotary tool applications in machine shops, jewelers' benches, and general maintenance settings. The cylinder profile makes it well suited for polishing flat surfaces, shoulders, and shallow recesses. Medium-density wool felt holds compound without excessive loading and releases it evenly across the contact area. It is sold individually and compatible with standard 1/8-inch collets found on most rotary tools and die grinders.

Installation Notes

Secure the 1/8-inch shank fully into the collet of the rotary tool or die grinder before operation. Ensure the collet nut is tightened to the tool manufacturer's specification before running the spindle. Apply polishing compound directly to the felt bob or to the workpiece surface rather than over-loading the bob. Inspect the wool felt for wear or separation from the shank before each use and replace if deterioration is visible.
