        abstract = {Machining of hardened die steels such as AISI H11 presents significant challenges due to high cutting temperatures, rapid tool wear, and deterioration of surface quality. Improving the performance and durability of cutting tools is therefore essential for achieving efficient and cost-effective machining. This study investigates the effect of cryogenic treatment on the performance of coated tungsten carbide cutting tools during the turning of AISI H11 steel. TiN- and TiAlN-coated tools were subjected to deep cryogenic treatment and their machining behavior was compared with conventionally treated tools under identical cutting conditions. The influence of cryogenic treatment on tool wear, surface roughness, cutting forces, and cutting temperature was systematically evaluated. The results indicate that cryogenically treated tools exhibit improved wear resistance, reduced cutting forces, and lower cutting temperatures, leading to enhanced tool life and better surface finish of the machined components. The improvement in performance is attributed to microstructural refinement, reduced residual stresses, and improved coating–substrate adhesion resulting from cryogenic treatment. This study demonstrates that cryogenic treatment is an effective and sustainable approach for enhancing the machining performance of coated tungsten carbide tools when turning AISI H11 steel, making it a promising technique for industrial die and mold manufacturing applications.},
