These roll taps are recommended for high speed machining 20 to 50 m / min. Cemented Carbide Taps ●Roll form processing of stainless steel and thermal refined materials up to 40 HRC are now possible. ⑤ ●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.
