Hard coatings (2) and methods of making the hard coatings (2) comprising aluminum titanium nitride which are usable on cutting tools are disclosed. The coatings (2) include at least one aluminum titanium nitride layer (6) having between about 0 and about 15 weight percent hexagonal phase and a composition of (AlxTi1-x)N, where x is in the range of about 0.53 to about 0.58 moles. L'invention concerne des revêtements durs (2) et des procédés de fabrication de revêtements durs (2) comprenant un nitrure d'aluminium et de titane, utilisés en outillage de coupe. Les revêtements durs (2) comprennent au moins une couche de nitrure d'aluminium et de titane (6) présentant une phase hexagonale d'environ 0 à 15 % en poids et une composition de (AlxTi1-x)N dans laquelle x est dans une plage comprise entre environ 0,53 et 0,58 mole.
