    Abstract: PROBLEM TO BE SOLVED: To provide an insert for milling to provide various wear types with excellent cutting performance during high speed cutting of an alloy steel and a tool steel and milling of a cured steel. SOLUTION: A cutting tool insert is formed of a body made of cemented carbide and a covering film and especially suitable for high speed milling for an alloy steel and a tool steel and milling for milling a cured steel. The composition of the cemented alloy body is 7.9-8.6 wt.% preferably 8.0-8.5 wt.% Co, 0.5-2.1 wt.% in a total or preferably 0.7-1.8 wt.% cubic carbide of Ta and Nb, 1.0-12.0 preferably 1.5-11.4 wt.%, average chip length 0.4-0.9 μm preferably 0.5-0.8 μm WC, binder phase contains W corresponding to S value 0.81-0.95 preferably 0.82-0.94. The covering film is formed of Ti x Al y N layer, 0.8≤x+y≤1.2, 0.25≤x/y≤1.45 preferably 0.33≤x/y≤1.1, a film thickness is 0.5-7 μm preferably 1-6 μm, and columnar grains are contained.

    Abstract: PROBLEM TO BE SOLVED: To provide a cutting tool insert, a solid end mill or a drill including a substrate and a coating film. SOLUTION: The coating film is constituted of one or a plurality of layers of a refractory compound. At least one of layers of the refractory compound contains a cubic crystal (Me, Si)X phase where Me refers to one or more of Ti, V, Cr, Zr, Nb, Mo, Hf, Ta and Al, and X refers to one or more of elements N, C, O and B. A ratio R (X ratio/Me ratio) of a c-MeSiX phase is 0.5-1.0, and X contains O+B by a quantity less than 30 atom%. The invention is especially useful in application for machining metal with producing small chips and for a hard material to be machined, for example in copy-milling through the use of the solid end mill, milling an insert or boring hardened steel.
