A coated tool includes a base and a coating layer on the base. The coating layer includes a cubic crystal that includes one or more kinds of elements selected from Groups 4, 5 and 6 in the periodic table, Al, Si, B, Y and Mn, and one or more kinds of elements selected from C, N and O. A maximum peak is in a range of 50° or more in a distribution of X-ray intensity (111) at α axis of a pole figure, the X-ray intensity regarding a (111) plane of the cubic crystal. The intensity at the maximum peak is Imax, a peak width at 0.8 Imax of the maximum peak is 20° or more, and the intensity at 90° is 0.78 Imax or more. A cutting tool includes a holder which includes a pocket at an end, and the coated tool in the pocket.

The present invention relates to a tool (100) for machining workpieces (200), comprising a surface (110) which is at least partially covered by a PVD deposited wear-resistant coating (120), said wear resistant coating (120) comprising one or more wear-resistant layers (121, 122), the coating having a modulus of elasticity, E, which is in a range 300 GPa≤E<350 GPa, and further having a hardness, H, which is greater than 30 GPa.

A coating comprising a bottom layer comprising a hard physical vapor deposition (PVD) coating applied to the end mill. The bottom layer has an edge-prep and polished top surface with reoriented cutting forces. The coating includes a top layer comprising a friction reducing coating applied to the top surface of the bottom layer to prevent or minimize titanium or titanium alloy adhesion to the end mill during milling operations of a metal object comprising the titanium or titanium alloy. The coating has a chemical composition which has inertness toward titanium or titanium alloy. A cutter tool and method are also provided.

One aspect of the disclosure relates to a cutting tool for forming a final opening in a stack that includes at least two layers and a pilot opening having a pilot-opening dimension and extending through at least one of the at least two layers. The cutting tool includes a shank. The cutting tool also includes a first portion including at least one of a first coating or the first coating and a second coating, wherein the first coating at least partially covers the first portion. The cutting tool also includes a second portion between the shank and the first portion, wherein the second portion includes the second coating, and wherein the second coating at least partially covers the second portion.
