Roll Tap "HP+RZ/OL+RZ"
High-performance roll tap for dry machining.
We would like to introduce the roll tap 'HP+RZ/OL+RZ' that adopts a torque reduction raised tap specification. "HP+RZ" is a high-performance roll tap that can be used in high-speed areas. It is capable of machining stainless steel and heat-treated materials. "OL+RZ" is a roll tap for dry machining that achieves high-speed machining in completely dry processing of thin steel plates (including burr processing). 【Features of HP+RZ】 ■ Usable in high-speed areas (achieves 40m/min for steel materials) ■ Capable of machining stainless steel and heat-treated materials (up to 40HRC) ■ Machining torque is reduced by over 20%, significantly increasing lifespan ■ Usable with water-soluble cutting oils *For more details, please refer to the PDF document or feel free to contact us.
