Abstract
An end mill for cutting machining of metals has two or more main cutting edges (5'). The partitions between the main cutting edges circumferentially around the rotation axis of the end mill are different. The maximum angle value of a partition angle is defined by the formula: omega n = (360 +/- sigma )/z where omega n is the partition angle, sigma is a constant which shall not exceed 90 and z is the number of main cutting edges. However, the smallest difference between at least two partition angles shall not be less than 4 DEG /z. By this differentiated partition, vibrations are avoided to a high degree, which otherwise sometimes occur at known end mills.
