Abstract: The present invention relates to a cutting tool insert comprising a substrate and a coating including at least one layer of TiB2. The TiB2-layer has a fibrous microstructure where the grains are 5-50 nm, preferably 10-30 nm, in diameter and a length more than 250 nm, preferably more than 400 nm long, with a length to diameter ratio, 1/d > 2, preferably > 5, and oriented essentially perpendicularly to the surface of the substrate.

Abstract: The present invention relates to a cutting tool insert, solid end mill, or drill, comprising a substrate and a coating. The coating is composed of one or more layers of refractory compounds of which at least one layer comprises a cubic (Me,Si)X phase, where Me is one or more of the elements Ti, V, Cr, Zr, Nb, Mo, Hf, Ta and Al, and X is one or more of the elements N, C, O or B. The ratio R = (at-% X)/(at-% Me) of the c-MeSiX phase is between 0.5 and 1.0 and X contains less than 30 at-% of O + B. This invention is particularly useful in metal machining 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.

Abstract: The present invention relates to a cutting tool insert, solid end mill, or drill, comprising a substrate and a coating. The coating is composed of one or more layers of refractory compounds of which at least one layer comprises a h-Me1Me2X phase, where Me 1 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-% X)/(at-% Me 1 + at-% Me2) of the h-Me1Me2X phase is between 0.5 and 1.0, preferably between 0.8 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.

Abstract: The present invention relates to a cutting tool insert comprising a substrate and a coating. The coating is composed of one or more layers of refractory compounds of which at least one layer comprises a so called precipitation hardened (TiyAlxMe1-x-y)N based layer, where Me is one of the element Zr, Hf, V, Nb, Ta, Cr, Mo, W or Si. This layer is defined by: x is between 0.50 and 0.80, the ratio, R=x/(x+y), is between 0.50 and 0.85, the sum of Ti and Al subscript, S=x+y, is between 0.7 and 1.0 the ratio of the peak width, F10/90, (FW10%M or FW90%M meaning Full Width at 10% and 90% of the maximum peak value reduced with the background) measured using X-ray diffraction with Cu K alpha radiation of the 200 peak at approximately 43 DEG 2&thetas; of the (TiyAlxMe1-x-y)N coating is higher than 7.5, the ratio between the area of the h-AlN (100) peak at approximately 33 DEG 2&thetas; (=A(h-AlN)100) and the c-(TiyAlxMe1-x-y)N (200) peak at approximately 43 DEG 2&thetas; (=A(c-(Ti,Al,Me)N)200) called K, i.e. K=A(h-AlN)100/ A(c-(Ti,Al,Me)N)200, and K is between 0 and 0.3 and the layer consists of a single (TiyAlxMe1-x-y)N (200) peak.
