End mill

An end mill for metal cutting comprises a body (1) having a cutting section (6) extending axially rearward from a front end (2), the cutting section (6) comprising a plurality of teeth (7) projecting radially and extending axially. Each tooth (7) of the plurality of teeth (7) comprises a front cutting edge (13) extending axially rearward and radially outward from an axially forward point (14, 14a) of the respective cutting edge (12). When the body (1) rotates, the cutting edges (12) of each tooth (7) form a line of intersection in a central plane containing the central longitudinal axis (4). Each front cutting edge (13) is interrupted by at least two chip-dividing grooves (17) such that the line of intersection of the front cutting edge (13) with the interrupted chip-dividing grooves (17) comprises: outer crests (22), each outer crest (22) being located on an imaginary convex curve (24); at least two inner grooves (23); and curved portions (25), each extending from a respective one of the at least two grooves
