Value Collection 516142 Oval Wool Felt Polishing Bob 1 in

Product Description

The Value Collection 516142 is a mounted polishing bob designed for precision surface finishing, deburring, and polishing tasks on metal, plastic, and composite materials. Constructed from hard-density wool felt, this oval-shaped bob delivers consistent contact pressure and controlled material removal when chucked into a rotary tool, die grinder, or drill press. The 1/4-inch shank seats securely in standard collets and chucks, while the 1-inch maximum diameter and 1-inch head length provide reach into contoured surfaces and tight geometries. At under 0.04 pounds, the bob adds negligible rotating mass, supporting stable high-speed operation.

This mounted polishing bob is suited for toolroom, maintenance, and production finishing applications where a consistent, repeatable polish is required on small or detailed workpieces. Typical use cases include polishing mold cavities, deburring machined bores, and surface-finishing jewelry, instrument components, or precision hardware. The hard-density wool felt construction is appropriate for applying polishing compounds to achieve a refined surface finish without aggressive material removal. Machinists, toolmakers, and metalworking professionals are the primary installers and users of this accessory.

Key Features

• Oval bob shape conforms to contoured and recessed surfaces for even polish contact
• Hard-density wool felt construction provides firm, controlled polishing action
• 1/4-inch shank diameter fits standard die grinder collets and drill chuck sizes
• 1-inch maximum diameter and 1-inch head length suit small-bore and cavity work
• 2-inch shank length provides clearance when working in deeper recesses
• Lightweight at approximately 0.04 pounds, minimizing rotational imbalance

Compatibility

Designed for use with any rotary tool, die grinder, or drill accepting a standard 1/4-inch shank mounted accessory.

Installation Notes

A licensed or experienced machinist or toolroom technician should mount the bob in a properly rated collet or chuck rated for the intended RPM. Ensure the rotary tool is powered off and fully stopped before inserting or removing the shank. Inspect the wool felt head for wear, fraying, or imbalance before each use, and do not exceed the tool manufacturer's maximum recommended RPM for mounted accessories of this diameter. Apply polishing compound sparingly to the felt surface rather than to the workpiece to maintain even distribution.
