A helical sector gear having a body and a gear segment having a plurality of helical teeth. The gear segment has a toothed sector, on which all of the helical teeth are formed, and spacing segments on the opposite circumferential ends of the toothed sector. Each of the spacing segments has a circumferential surface, which is longer than a pitch of the helical teeth, and a radial surface that is formed in a helical manner that conforms to the helix angle of helical teeth. A die set for forming the helical sector gear and a related method are also provided.
