CNMG120408HQ CA025P (TMH00091)

The CNMG120408HQ CA025P is a premium indexable turning insert designed for high-speed finishing and semi-finishing of steel. The CA025P nano-layer CVD-coated carbide grade delivers exceptional wear resistance and surface finish quality at elevated cutting speeds, while the HQ chipbreaker geometry — with its aggressive curved chip-forming profile — provides outstanding chip control even at high feeds. The bright gold coating is clearly visible in the image, indicating a premium TiCN/Al2O3/TiN multilayer CVD coating.
