Threading Taps

Heat treated and heat-resistant steels
Rm < 1.000 N/mm²
 MACHINE TAP WITH INTERNAL COOLANT FEED AND AXIAL EXIT
 Facilitates chip evacuation and improves cooling in cutting area.
 With 38º right-hand spiral flutes, driving the chips to the back, increased
      flute length.      Threaded length: 10 threads.
 Starting from the 5th thread, back tapered thread portion to reduce friction
      and improve swarf clearance.
