Winona Van Norman Porcelain Cylinder Filler Media: Very Small High-Luster Polishing (2.5mm x 8mm) (3lbs)

The Winona Van Norman Very Small Porcelain Cylinder Filler Media is the ultimate solution for achieving a precise, mirror-like finish on the most delicate and intricate parts. Graded to an approximate size of 2.5mm×8mm (3/32"×5/16"), this high-density, non-abrasive media is designed for the final, high-luster polishing and burnishing stage in mass finishing. Its smooth, durable cylindrical shape is engineered to reach internal recesses, break minor edges, and impart a flawless, uniform polish without aggressive material removal or changing critical dimensional tolerances. Perfect for jewelry, precision-machined parts, and as a superior filler for rock tumbling.

• Very Small Size: Cylindrical media measuring approximately 2.5mm×8mm (3/32"×5/16") is ideal for accessing small holes, slots, and internal contours where larger media cannot reach.
• High-Luster Burnishing Media: Non-abrasive, high-density porcelain composition works with polishing compounds to deliver a smooth, flawless, mirror-like, and high-color finish on all metal types.
• Non-Aggressive Finishing: Will not etch, cut, or change the dimensional tolerance of precision parts, making it essential for final stage processing of delicate components
• Superior Durability and Reusability: Made from highly durable porcelain, this media is longer-lasting and more wear-resistant than standard ceramic media, offering cost-effective, repeated use.
• Multi-Use Filler for Tumblers: Functions as a superior filler media for rock and gemstone tumblers, cushioning the load, reducing noise, and efficiently carrying polishing grit across all surfaces.
• Gentle Deburring and Edge Breaking: Subtly removes small burrs and feathered edges from machined parts, leaving a smooth, cosmetically friendly surface without damaging the component's integrity.
• Versatile Application: Highly effective in vibratory tumblers, rotary tumblers, and high-energy finishing machines for pre-plating/coating preparation, deburring, and final polishing.
