Optimized primarily for the high-demand processing of cast iron (ISO K-class spectrum) and high-hardness steels, this insert offers extreme resistance against plastic deformation, thermal micro-cracking, and thermal shock. The high-performance coating layers act as an impenetrable thermal barrier, dramatically suppressing abrasive wear during prolonged cutting cycles.
