Rainbow Diamond coating

Rainbow Diamond is an advanced, diamond-like coating independently developed by Kuiding, which can be combined with metallic layers to expand its range of applications. It is ideal for non-ferrous soft materials and aluminum processing, effectively reducing tool adhesion, improving edge quality, and significantly extending tool life—achieving over twice the tool lifespan when machining pure aluminum.

• Smooth Surface & Low Friction
• High Wear Resistance & Anti-Sticking
• Excellent Chip Evacuation
• Milling & Turning Tools: Suitable for machining non-ferrous materials such as aluminum substrates, LED heat sink aluminum boards, PCB rigid and flexible boards, copper, lead-free copper, and optical plastics.
