Value Collection 516120 Mounted Polishing Bob Wool Felt

Product Description

The VALUE COLLECTION 516120 is a cylinder-shaped mounted polishing bob designed for precision surface finishing and polishing work. Constructed from medium-density wool felt, this bob mounts directly to a rotary tool or die grinder via its 0.125 inch shank and delivers consistent, controlled polishing action on metal, wood, plastic, and similar materials. The cylindrical head profile makes it well-suited for polishing flat surfaces, contoured edges, and recessed areas where a spherical or tapered bob would be less effective. Machinists, tool and die makers, jewelers, and finishing tradespeople reach for this type of bob when a smooth, repeatable surface finish is the goal.

This mounted polishing bob is used in light industrial, machine shop, and bench work applications where fine finishing is required. It fits standard rotary tools and pneumatic or electric die grinders that accept a 0.125 inch shank. Typical applications include deburring, light blending, and final polishing of machined components, castings, and fabricated parts. The medium-density felt holds polishing compounds well without breaking down prematurely under normal operating loads.

Key Features

• Cylinder shape provides uniform contact across flat and contoured surfaces
• Medium-density wool felt construction holds polishing compound effectively
• 0.125 inch shank diameter fits standard rotary tools and die grinders
• 0.5 inch maximum head diameter suited for detail and precision finishing work
• 1 inch head length offers adequate surface area for efficient material coverage
• 2 inch shank length provides clearance for deep or recessed work areas

Compatibility

Designed for use with rotary tools and die grinders that accept a 0.125 inch diameter shank. Suitable for polishing metal, wood, plastic, and composite surfaces in bench work and light industrial finishing applications.

Installation Notes

Install the shank securely into the collet or chuck of the rotary tool before operation, and confirm the collet is properly tightened before applying power. Apply polishing compound directly to the felt bob or to the workpiece surface before use. Do not exceed the maximum RPM rating of the rotary tool for this shank diameter. Inspect the felt bob for wear or fraying before each use and replace if the material shows significant deterioration.
