Second Generation Inveio® Technology With the introduction of the second generation Inveio® technology, the benefits of uni-directional coating have been further developed. Improved crystal orientation makes for an even more consistent performance and significantly improved wear resistance and tool life.

Sustainable Steel Turning An average of 25% tool life increase combined with a reliable and predictable performance helps minimize both insert and workpiece material waste, necessary preconditions for sustainable machining. Moreover, its carbide substrate contains a high proportion of recycled carbide material, making them one of the most environment-friendly grades.
