25〜35HRC Product Features

  • The HP+RZ/HP-RZ roll taps are suitable for processing steel materials with a hardness of 35 HRC or less and light alloys. These roll taps are recommended for high speed machining 20 to 50 m / min.

●Roll form processing of stainless steel and thermal refined materials up to 40 HRC are now possible.

  • The roll form tapping torque has been reduced by 20% or more, making it possible to significantly improve tool life compared with conventional roll form tap products.

●The HP+RZ/HP-RZ taps make it possible to use a water soluble cutting fluid.

Using an optimal design on the chamfer portion, the Chamfer portion works from the first thread lobe.

HP+RZ forms the internal thread from the first chamfer

portion, reducing the processing burden on each thread Impressions on the lobes of the HP + RZ
