A method for manufacturing a contoured hole (8), the hole being manufactured in a wall (2), the wall comprising a first surface (3), a second surface (4), and a wall thickness between the wall first and second surface. The comprises manufacturing a first non-penetrating hole (20) extending from the first surface and into the wall, wherein a distal end of the first hole is located within the wall such that the first hole does not penetrate the wall second surface, and manufacturing a through hole (40), wherein the through hole is fluidly connected with first hole and penetrates the wall second surface. |
