1. A method for producing a helical metal body, the method comprising:
producing a blank using a subtractive machining process; and
introducing at least one recess into the blank using the subtractive machining process, wherein the at least one recess defines a circumferential helix, wherein respectively mutually adjacent windings of the circumferential helix are at least one of: spaced from each other, or are electrically insulated from each other, wherein the subtractive machining process is implemented with a subtractive processing device, wherein the subtractive machining process includes:
rotating the helical metal body about its longitudinal axis; and
moving the helical metal body during the rotating in a translatory manner relative to the subtractive processing device parallel to its longitudinal axis.
