    摘要: The invention relates to a screw tap (1) having a shaft (100). According to the invention, the function of the screw tap drive in applying cutting force is improved in that a recess is introduced into the front end (4) of the shaft (100), the recess extending with its negative cross-section in the axial direction and suited to receiving a force-fit drive with a positive cross section corresponding to the recess (5).
