Ideal for forged products and tempered materials like S48C to S55C at 25 to 35HRC.
Utilizing a unique high speed steel material and a special coating has created an excellent wear resistance with longer tool life.
The special threaded portion design makes it effective against flute chipping at the full thread portion of the tap. This new design helps reduce tapping torque and frictional resistance to maintain the screw thread guide properties.
The new design allows for a longer tool projection to accommodate the discharge of the chips and prevents them from being entangled with the holder.
