    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.

    Abstract: PROBLEM TO BE SOLVED: To provide a cutting tip, which is a coated cutting tool (coating tip) for turning of steel at high cutting speeds, having excellent deformation resistance, high wear resistance, and toughness. SOLUTION: The coated cutting tool comprises a cemented carbide body coated with α-Al 2 O 3 of (006) orientation. The cemented carbide body contains metal forming 4.5-6.5 wt.% of Co and 3-10 wt.% of cubic carbide. A value S is 0.77-0.92 and coercive force is 10-20 kA/m. Thickness of α-Al 2 O 3 layer is within a range of 7-12 μm, and the layer is composed of columnar crystal grains having a ratio of length/width within a range of 2-12 and formed on an MTCVD Ti(C, N) layer having thickness of 4-12 μm by evaporation. An Alumina layer is oriented (006). In the tool with black and shining appearance, the alumina layer becomes the uppermost layer and Ra is made to be less than 1 μm by wet blasting.

    Abstract: PROBLEM TO BE SOLVED: To provide a cutting tool insert including base material and coating, a solid end mill, or a drill.
    SOLUTION: The coating is composed of one or more layers of refractory compounds of which at least one layer comprises a h-Me1Me2X phase, where Me1 is one or more of the elements V, Cr, Nb, and Ta and Me2 is one or more of the elements Ti, Zr, Hf, Al, and Si and X is one or more of the elements N, C, O or B. The ratio R=(at-% to X)/(at-% of Me + at-% of Me2) of the h-Me1Me2X phase is between 0.5 and 1.0, preferably between 0.75 and 1.0 and X contains less than 30 at-% of O + B. This invention is particularly useful in metal cutting applications where the chip thickness is small and the work material is hard e.g. copy milling using solid end mills, insert milling cutters or drilling of hardened steels.
