<p>In a first aspect, the invention relates to a milling cutter head, which has, on one hand, an external envelope surface (10), which has a rotationally symmetrical basic shape in respect of a central axis (C), and includes a plurality of peripherally spaced-apart cutting edges (11 ) and chip flutes (12), and, on the other hand, two axially spaced-apart ends (8, 9) in which hollow spaces (20) open, which are spaced-apart by a partition wall (25) in which a through hole (17) is formed, which mouths in bottom surfaces (21 ) in the hollow spaces (20). According to the invention, the cross-section area of the individual hollow space (20), in a plane perpendicular to the centre axis (C), amounts to at least 25 % of the total cross-section area of the cutter head, such as this is defined by the greatest diameter (D1 ) of the envelope surface (10).</p> |
