Achieve a mirror-like surface with OTEC’s walnut shell granulate – a high-quality dry polishing media designed for the ECO-Maxi disc finishing system.

This granulate adapts to the shape of each workpiece and reaches effectively into even the most intricate details. It is impregnated with a polishing paste, eliminating the need to add extra paste during the first 3–4 polishing cycles.

Ideal for high-gloss polishing of jewellery and components made of precious metals, titanium, and steel alloys.

When should you refresh with preparation paste?

The granulate needs new paste when it:

• develops a shiny surface
• stops circulating and settles along the edge
• feels dry and no longer sticks to your hand

Choose the right grain size for your polishing process:

• H1/100 – Coarse: suitable for initial rough polishing
• H1/200 – Medium: reduces grinding marks and prepares the surface for fine polishing
• H1/300 – Fine: used for fine polishing
• H1/400 – Extra fine: creates an almost finished surface with high shine
• H1/500 – Ultra fine: delivers a flawless, mirror-bright finish

Perfect for professional jewellers and workshops looking for an efficient, gentle, and detailed polishing result with a brilliant final shine.
