A milling tool has a tool shank and a cutting head fastened to the forward end of the tool shank by way of a clamping connection. The clamping connection has a protrusion with clamping faces, and a recess with centering faces that interact with the clamping faces. Each of the centering faces has a first region where the centering faces are spaced from a longitudinal axis of the tool shank by a first distance and a second region at a smaller distance. The first region merges into the second region. The clamping faces of the protrusion are introducible into the recess between the first regions of the centering faces and are movable, by rotation of the cutting head about the longitudinal axis, into a clamping position in which the clamping faces interact in a force-fit with the second regions of the centering faces.
A milling tool, comprising:
A method for fastening a cutting head to a tool shank of a milling tool, the tool shank having a longitudinal axis and the cutting head having a plurality of cutting edges for machining a work piece, wherein the tool shank and the cutting head are connected to one another via a clamping connection, the clamping connection having a protrusion formed circumferentially with a plurality of clamping faces, flattened portions between adjacent ones of the clamping faces, and a recess formed circumferentially with a plurality of centering faces configured to interact with the clamping faces, and stop portions projecting radially inward relative to the centering faces, the stop portions being between the centering faces wherein the centering faces each have a first region in which the centering faces are located at a first distance from the longitudinal axis, in a section perpendicular to the longitudinal axis, and the first region merges into a second region in which the centering faces are at a smaller second distance from the longitudinal axis in the section perpendicular to the longitudinal axis,
