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. |
