25〜35HRC Product Features

  • The OL+RZ/OL-RZ roll taps have made it possible tapping without lubrication in the sizes M6 and smaller. 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 accuracy is stabilized even under severe conditions.

●For blind hole tapping, please select the HP + RZ / HP-RZ tap series as an alternative item.
