Porcelain Balls 4mm Diameter-1 Lb Pack

Porcelain ball media in a 4 mm diameter for mass finishing and deburring of jewelry, castings, and fabricated metal parts. This micro-abrasive ceramic cuts, cleans, and leaves an extremely smooth surface that is bright but not mirror-reflective. A lighter alternative to steel shot, porcelain media is well suited for smaller vibratory bowls or rotary barrels where machine weight limits apply. Long service life and gentle action make it a smart choice for preserving fine details and delicate edges. Sold in a 1 lb pack. Use wet with a suitable detergent or burnishing compound.

Specifications

Applications

• Cutting and cleaning castings and fabricated parts
• Smoothing metal surfaces prior to final polish
• Lighter-weight alternative to steel shot where marring is a concern

Notes

• Use wet with a small amount of detergent or burnishing compound.

• For best results, consider running a mix of sizes to improve media coverage and tumbling action.
