Achieving processing for medium-hard steel equivalent to 40HRC! Evolved roll taps.

The "EHRZ" is a roll tap suitable for machining medium-hard carbon steel and alloy steel (up to 40HRC). 【Features】 ■ Adopts the common "semi-long shape" of the Z-PRO brand! Enables reliable external lubrication due to the appropriate overall length. Achieves good internal thread processing. ■ Improved low torque! Prevents low torque and welding through a "unique thread relief shape" and surface treatment technology that maximizes the effect of the coating. ■ Adopts an optimal groove shape! Wider groove width than conventional designs enhances lubrication and cooling effects due to high oil supply efficiency. ■ Specifications suitable for medium-hard steel materials! By using a special coating and a base material suitable for the workpiece, it is also applicable to medium-hard steel materials and stainless steel below 40HRC. *For more details, please refer to the PDF document or feel free to contact us. -------------------------------------------------- Solving machining concerns!
