These taps are designed for thin steel sheet screw threads or steel with a relatively short screw thread length. ●Increased shank accuracy and an optimum lobe portion design produces a smooth thread forming action and the internal thread ⑤ accuracy is stabilized even under severe conditions. ●For blind hole tapping, please select the HP + RZ / HP-RZ tap series as an alternative item.
