Threading Taps

MACHINE TAP WITH INTERNAL COOLANT FEED AND AXIAL EXIT
Facilitates chip evacuation and improves cooling in cutting area.
Machine tap 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.
Chamfer lead 2.5 threads (DIN-Form C).      Rake angle 8º÷10º.
