A metal cutting insert has a substrate body of cemented carbide, cermet, or ceramic and at least one cutting edge defined between a rake face and a relief face. The cutting insert has a CVD coating including a layer of aluminum titanium nitride having a cubic face centered lattice structure, represented by a formula (AlTiM)CNwherein a stoichiometry coefficient of aluminum is 0.30<x<0.95, wherein M is at least one element selected from the group consisting of Cl and Ar, with a stoichiometry coefficient of which is 0≤y<0.01, and wherein a stoichiometry coefficient of carbon is 0≤z<0.3. The (AlTiM)CNlayer satisfies a relationship 10<|S-S|<500 MPa wherein Sis the residual stress measured on the rake face, and Sis the residual stress measured on the relief face.
