Abstract: The invention relates to a machining tool (1) comprising the following: a main part (2), at least one seat (3) formed on the main part (2), a securing screw (5), and a cutting insert (4) which is secured to the seat (3). The seat (3) has a base surface (3a) for supporting a lower face of the cutting insert (4) and a lateral contact surface (3b). The base surface (3a) is equipped with a bore (6) for receiving the securing screw (5), said bore having a threaded bore section (6a) and a thread-free bore section (6b) closer to the base surface (3a). The cutting insert (4) is secured to the seat (3) such that the head portion (5b) of the securing screw (5) rests against the through-hole (7) of the cutting insert (4), a threaded section (5a) of the securing screw (5) interacts with the threaded bore section (6a), and the securing screw (5) is elastically deflected such that a thread-free shaft section (5c) rest against the thread-free bore section (6b) on a face facing away from the lateral contact surface (3b) and is spaced from the thread-free bore section (6b) on the face facing the lateral contact surface (3b).

Abstract: A milling tool (1) is provided, comprising: a tool shank (2) with a longitudinal axis (L), and a cutting head (4), which is secured at an end face to the tool shank (2) and has a plurality of cutting edges (4a) for the machining of a workpiece. The tool shank (2) and the cutting head (4) are connected to one another by way of a clamping connection. The clamping connection has a projection (11) with a plurality of clamping areas (12) around the circumference and a clearance (3) with a plurality of centring areas (6) around the circumference, interacting with the clamping areas (12). The centring areas (6) have in each case a first region (6a), where the centring areas (6) are at a first distance from the longitudinal axis (L) in a section perpendicular to the longitudinal axis (L), and the first region (6a) goes over into a second region (6b), where the centring areas (6) are at a smaller, second distance from the longitudinal axis (L) in the section perpendicular to the longitudinal axis (L), and so the clamping areas (12) of the projection (11) can be inserted into the clearance (3) between the first regions (6a) of the centring areas (6) and, by rotation of the cutting head (4) in relation to the tool shank (2) about the longitudinal axis (L), can be moved into a clamping position, in which the clamping areas (12) interact in a frictionally engaging manner with the second regions (6b) of the centring areas (6).
