Ferg Threading Taps T192

Threading Taps

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 14º÷16º.
