転削工具。[Claims for Utility Model Registration] A throw-away tip 7 is attached to the outer circumferential portion of the cylindrical tool body 2, and an outer circumferential cutter 11 and an inner circumferential cutter 12 are attached to the outer ridgeline portion of the throw-away tip 7. In the milling tool for diagonal descent cutting, the outer circumferential cutting edge 11 includes a vertical cutting edge 11a that is substantially perpendicular to the diametrical line of the tool body 2, and a terminal end side of the vertical cutting edge 11a. The inner circumferential blade 12 is composed of a horizontal blade 12a and an inclined blade 12b, and the horizontal blade 12a is shorter than the vertical blade 11a. The hook is perpendicular to the starting end side of the vertical blade 11a, and the inclined blade 12b is provided adjacent to the horizontal blade 12a, and the inclination angle α with respect to the diametrical line of the tool body 2 is within the range of α = 6° to 20°. A milling tool for diagonal descent cutting, characterized in that it is set as follows.
