Abstract: A multi-part modular tool rotatable about a longitudinal tool axis (A), comprising: a machining head; a first holding element comprising a body elongated along the longitudinal axis (A) of the tool, in which a passage extends along the longitudinal axis (A) of the tool; a second holding element which can extend in the passage of the first holding element; wherein the machining head can be connected to the second holding element in such a way that the machining head is fixed firmly to the first holding element at least in the axial direction (A) and/or in the radial direction (R), and wherein the passage of the first holding element and the second holding element are adapted to one another such that during a connection process in which the machining head is connected to the second holding element, the second holding element is movable relative to the first holding element.

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.
