Brand: High-Quality Diamond Grinding Paste Particle sizes (coarse to fine): W40 320, W28 400, W20 600, W14 800, W10 1000, W7 1500, W5 2000, W3.5 3000, W2.5 4000, W1.5 6000, W1.0 8000, W0.5 10000 Why you need it: Different roughness of workpiece surfaces requires corresponding pastes. Suitable for high precision polishing of jade, watches, lighters, jewelry and metals. Key benefits: oil soluble abrasive; easy to use; resin wax and diamond composition; oil-based to prevent contamination; environmentally friendly. How it works: Start with a coarse grade such as W40 and progress through finer grades to achieve a mirror finish. Environment and care: high efficiency and comfortable to use; non corrosive. Use with a short felt or wool polishing head. No special detergent needed; wipe with water after use. Materials: oil-soluble abrasive made from resin, wax and diamond particles; oil-based for smooth operation and reduced residue. Recommended use scenarios: jewelry finishing, watch case polishing, jade smoothing, metal parts finishing. Usage tips: apply a small amount to the polishing head; keep the surface lubricated; move through the grade sequence to reach optimal mirror results.
