In this study, a comparison of the wear resistance of AlCrN, AlTiN, TiAlN, TiCN, and CrN PVD coatings deposited on hard-metal WC-Co wood milling cutters was performed. Real industrial application experiments were performed for the milling of oak wood. During the tests, the roughness of the machined oak wood surface was inspected, and the cutter wear was measured after the experiments. Thickness, hardness, roughness, and coefficient of friction of the coatings were determined. It was found that deposition of CrN, AlCrN, and TiCN coatings could improve the wear resistance of the investigated cutter by factors of 3, 1.9, and 1.7, respectively. The performance differences and wear mechanisms were described in detail based on the properties of the coatings.
