<p>In a first aspect, the invention relates to a replaceable milling cutter head (2), which has, on one hand, an external, rotationally symmetrical envelope surface (10) having a plurality of spaced-apart cutting edges (11 ) and chip flutes (12), and, on the other hand, front and rear ends (8, 9), a hollow space (20) opening in the rear end (9) of the body, and an axial hole (17) extending all the way through a frame (30) of the milling cutter head and mouthing in a bottom surface (21 ) in said hollow space (20). According to the invention, the milling cutter head has a flat, pulley-like basic shape so far that the axial distance (L) between the two ends (8, 9) is at most half as large as the greatest outer diameter (D1 ) of the body, besides which the cross-section area of the hollow space (20), in a plane perpendicular to the centre axis (C) of the milling cutter head, amounts to at least 25 % of the total cross-section area of the body, such as this is determined by said outer diameter (D1 ). In a second aspect, the invention also relates to a milling cutter tool having such a milling cutter head.</p> |
