FIELD: metallurgy.
SUBSTANCE: group of inventions relates to use of hard-alloy cutting tool and to method of machining parts from titanium, titanium alloy or nickel-based alloy. Disclosed is use of hard alloy cutting tool having a substrate of cemented carbide containing graphite, with a gradient surface area of 50–400 mcm, having a binding phase gradient with the lowest binder phase content in the portion of the gradient surface area furthest from the center of the cutting tool, as a cutting tool for machining a part made from titanium, titanium alloy or nickel-based alloy, using cryogenic coolant. Said method involves using said cutting tool when feeding cryogenic coolant.
EFFECT: considerable increase of tool durability.
