Abstract
An end mill, preferably made of solid carbide, with a fastening section and a cutting area, in which the cutting area is formed by a core and three, four or five cutting edges arranged around core and running helically around the axis of rotation of the end mill, each one of which has a peripheral main cutting edge and a secondary cutting edge on the face of cutting area. In order to create an end mill simple to manufacture and optimized for drilling, at least one cutting edge on the face of cutting area has a single, flat or continuously curved front surface, which delimits the cutting edge in the longitudinal direction of the mill on face.
