A tool comprising a base body made of hard metal, cermet, ceramic, steel or high-speed steel, and a single-layer or multi-layer anti-wear protective coating formed on the base body in a PVD process, wherein the wear-resistant coating At least one layer of is a titanium-aluminum-nitride layer Ti x Al y N, where x + y = 1, and the titanium-aluminum-nitride layer may contain up to 5% by weight of other metals The Ti x Al y N layer may include a plurality of periodic alternating Ti x (A) Al y (A) N coats (A) and Ti x (B) Al y (B) Multi-coat substructure with N coats (B), where x (A) + y (A) = 1, x (B) + y (B) = 1, and coats ( The Al concentration y (B) in B) is up to 70 atomic% (y (B) ≤ 0.70), and the Al concentration y (B) in coats (B) is Al concentration in coats (A). (Y (B) = (y (A) + 0.10) to (y (A) + 0.25)), tool higher by 10-25 atomic percent than in Figure y (A).
