IDI provides high-quality diamond coated tools in both metric and imperial units.
DG coating is a multilayer diamond film coated on our special D17 substrate. With several layers of nano and micro crystalline diamond films overlapped each other, this coating solution provides not only the highest hardness of diamond but also smooth lubrication during graphite milling. Thanks to the finetuned coating process, our diamond film is now among the very best and most reliable diamond coating in the industry. In addition, IDI has a 100% inspection procedure after coating to ensure tool consistency and reliability. Our diamond coating, done in Europe, providing excellent tool life and stability for graphite milling, is used on all our diamond coated tools
