Abstract: A milling tool having an operating area that is rotatable about an operating axis of rotation for milling a workpiece. The operating area has at least one milling edge extending transversely to the circumferential direction (U) of an operating axis of rotation. At least one of the at least one milling edge includes at least one milling edge portion in which a milling edge profile (P), which is defined by the radial distance (F) between the milling edge and the operating axis of rotation along the milling edge, has a non linear progression. The milling edge in the milling edge portion has a chip space, which extends radially inward toward the operating axis of rotation in relation to the milling edge. The chip space has a chip space base that follows the milling edge profile (P) at least in portions in the milling edge portion with the non-linear milling edge profile (P).

Abstract: The invention relates to a cutting tool, in particular a milling tool, comprising a basic part and a head part adjoining the basic part and having a circumferential side and an end face, said basic part and head part having a common center axis and said head part comprising at least one lip having a cutting edge on the circumferential side. Said lip having a chip breaker surface adjoining the cutting edge of the circumferential side and comprising two chip breaker surface sections, the first chip breaker surface section being arranged at a first rake angle and the second chip breaker surface section being arranged at a second rake angle, said second rake angle being larger with respect to the first rake angle, and the first chip breaker surface section having an arch.
