The present invention mainly relates to an end mill for the water rough machining metal work, the end mill has a main flute (1-4) in the even of a spiral around the mill around, and the flute is relatively with respect to the mill axis smaller and relatively larger has a helix angle of the odd-numbered main flute is defined by them having a smaller helix angle with respect to the axis. Contact directly to the end face, close to the angle (a1, a2) of the main flute contiguous in the rotational direction is the even between the odd-numbered main flute (1, 3) and the even-numbered main flutes (2, 4) according thereto main flutes (2, 4) and according thereto is smaller than the distance between the peripheral angle (a2, a4) between the odd-numbered main flute (1, 3). All distances be different from each other between the peripheral angle of the mill end face according to the present invention to provide an end mill having the above-mentioned features, which can prevent vibration of the tool and more preferably by the intermittent engagement with the workpiece, do.
