<p>A tool for creating a profiled recess in a sandwich structure which comprises two thin rigid face sheets separated by a relatively thick, light and soft core, which tool comprises an elongate body (2) intended to rotate about its axial direction, and a cutting portion with at least one movable arm configuration (4) comprising a first arm portion (6) with a first and a second end, which first end is fastened articulatedly to the body and is pivotable in a substantially radial plane, a second arm portion (8), in the form of a cutting sheath (8), with a first end (D), a second end which is arranged for articulation relative to the body (2), is pivotable in a substantially radial plane and is arranged for movement in the axial direction, and a central portion to which the second end of the first arm portion (6) is articulatedly fastened, the distance between the articulation (A) of the first end of the first arm portion (6) and the articulation (C) of the central portion of the second arm portion (8) being in principle equal to the distance between the articulation (C) of the central portion of the second arm portion (8) and the articulation (B) at the latter' s second end. The invention also relates to a method for creating a profiled recess, intended for fastening purposes, in a sandwich structure, or for creating a hole through a sandwich structure.</p> |
