Abstract: A method for milling a threading of a screw or tapped hole. The threading has a cross section in the shape of a triangle with a truncated crest. The method includes milling a first flank (V1) of at least one spire of the thread by a first comb (A) of a milling tool (F). The teeth of the first comb (A) are spaced in relation to one another by a first pitch (P1). Then milling a second flank (V2) of at least one other spire of the thread by a second comb (B) of the milling tool (F), wherein the teeth of the second comb (B) are spaced in relation to one another by a second pitch (P2) equal to the first pitch (P1) and offset from the teeth of the first comb (A) by a phase displacement (DP). Then milling a truncated portion (V3) of the crest by a third comb (C) of the milling tool (F).
