FIELD: metallurgy.
SUBSTANCE: cutting tool comprises sintered body from cemented carbide, cubic boron nitride, cermet or ceramics, with Re-radius cutting edge, lateral and front surfaces, and single- or multilayer PVD-coating covering, at least, part of sintered body surface and bearing, at least, one oxide layer applied by cathodic arc deposition to cover, at least, sintered body surface part. Note here that edge Re-radius is smaller than 40 mcm, preferably, smaller than or equal to 30 mcm.
EFFECT: sufficient wear and thermochemical resistance.
