    Composition: With a multilayered PVD TiN-TiAlN coating, a high-quality, sub-micron, carbide substrate and a state-of-the-art surface condition, this grade gives the highest level of wear resistance at high cutting speeds.
    Application: First choice for alloyed and high-alloyed steels and cast irons. A state-of-the-art surface condition enables superior chip evacuation even when MQL is applied.
