Abstract
An end mill cutter (1; 100) includes a shaft (10) and a cutting head (20) with a number of helically running cutting webs (50), which are spaced apart from one another by means of flutes (30). The cutting webs (50) are divided into cutting web segments (60) at least over a portion of their length by a number of divider grooves (40) running helically in the opposite direction. The cutting head (20) is divided into a shaft-side cutting step (22) and an end face-side cutting step (24) adjoining the shaft-side cutting step (22) via a transition section (23) with a cutting diameter, which is smaller with respect to the shaft-side cutting step (22).
