Claim:
1. A milling tool, comprising: a tool shank having a longitudinal axis and a forward end; a cutting head fastened to said forward end of said tool shank, said cutting head having a plurality of cutting edges for machining a work piece; a clamping connection interconnecting said cutting head with said tool shank, said clamping connection having a protrusion circumferentially formed with a plurality of clamping faces, and a recess circumferentially formed with a plurality of centering faces configured to interact with said clamping faces; each of said centering faces in said recess having a first region and a second region, said first region of said centering faces being spaced apart from said longitudinal axis by a first spacing distance, in a section perpendicular to said longitudinal axis, said first region merging into said second region in which said centering faces are spaced apart from said longitudinal axis by a smaller second distance in the section perpendicular to said longitudinal axis, wherein said protrusion is introducible into said recess with said clamping faces between said first regions of said centering faces and said clamping face are movable, by rotation of said cutting head about said longitudinal axis relative to the tool shank, into a clamping position in which said clamping faces interact by way of a force-fit with said second regions of said centering faces; and said recess being formed with a plurality of radially inwardly projecting stop portions between said centering faces, said stop portions being configured for limiting a rotation of said cutting head about said longitudinal axis relative to said tool shank.
