The fine sand suction eye socket bead grinding head, or ball grinding head, is a specialized tool used for polishing and shaping materials like jade, amber, bodhi root, and similar semi-precious stones into round beads or balls.

These grinding heads are designed with a hollow center, creating a suction effect to hold the material in place during the polishing process. The exterior is coated with fine sand or abrasive particles that aid in shaping and smoothing the surface of the material, gradually forming it into a round bead or ball shape.

They are commonly used in jewelry making, crafting, and artisanal work to create uniformly shaped beads from raw materials. The abrasive coating on the grinding head allows for precise shaping and polishing , resulting in smooth, rounded beads suitable for various jewelry or decorative purposes.
