YG640 cemented carbide cutting insert, having a density of 13.10 ~ 13.30g/cm ³, flexural strength of not less than 2300 N / MM ², hardness of not less than 91.5HRA. Since YG640 cemented carbide cutting inserts with shock, antioxidant capacity. Suitable for large castings continuous, intermittent cutting and heat-resistant steel, high strength steel milling, planing. YG namely cobalt tungsten, tungsten carbide and cobalt. Such carbide toughness, hardness and wear resistance but less suitable for machining cast iron, bronze and other brittle materials. Commonly used grades are: YG8, YG6, YG3, which in turn made the tool for roughing, semi-finishing and finishing.
