    • The present invention relates to a method for drilling panels (P) by two or more drilling bits (51, 52, 53, 54) to drill at least one panel (P), wherein said drilling bits (51, 52, 53, 54) are installed on a drilling unit (2), movable along at least one movement direction (Z), and wherein each of said drilling bits (51, 52, 53, 54) is configured to assume an extracted position, in which it is capable of drilling said at least one panel (P), and a retracted position, in which it is not capable of drilling said at least one panel (P), wherein said method comprises the following steps:
      A. arranging two or more drilling bits (51, 52, 53, 54) in said extracted position;
      B. detecting (110) the relative position (Δ ij , Δ 32 , Δ 34 ) among said drilling bits (51, 52, 53, 54) in said extracted position or in said retracted position;
      C. handling (120, 130) said drilling unit (2) along said at least one movement direction (Z), so that said drilling bits (51, 52, 53, 54) in said extracted position carry out a respective hole (F) having a respective drilling depth (D, D1, D2, D3, D4); and
      D. switching (140) each of said drilling bits (51, 52, 53, 54) in the extracted position from said extracted position to said retracted position, any time each drilling bit (51, 52, 53, 54) reaches the respective drilling depth (D, D1, D2, D3, D4).
      The present invention also relates to a drilling machine (1), a computer program and a storage medium.
