摘要：A rotatable cutting tool (1) for machining of a honeycomb core, having a
longitudinal axis (A) around which it is rotatable in a direction of rotation (R), comprising: a front end (2); a rear end (3); a peripheral surface (4) extending between the front and rear ends; a set of helical flutes (5) formed in the peripheral surface at a first helix angle 45° ≤α ≤ 65°, having a first depth (d); a set of helical ridges (6), at least one helical groove (7) formed in the peripheral surface (4) at a second helix angle 90° < β ≤ 100°, having a second depth (d) which is smaller than the first depth, wherein the at least one helical groove intersects the helical ridges so that a plurality of cutting teeth (11) are formed on each helical ridge, wherein each cutting tooth comprises a second ridge (10) formed in a transition between two lands (8), a cutting edge (9) and a clearance edge (16) formed in a transition between one of said lands and a helical flute, wherein the second ridge, the cutting edge and the clearance edge join in a tooth tip (12) constituting the radially outermost point of the cutting tooth.
