SPIRAL FLUTE TAPS:
1.The SFT series is designed with about 39° helical angle, which permits smooth chips exhaust during tapping.
2.Suitable for tapping deep holes and blind holes with, continous chips exhause. Applicable materials include carbon steel and alloy steel.
3.Accuracy of shapes, sizes and threads are based on hand tap. Lead thread length is 2.5 threads.

|
SPIRAL FLUTE TAPS:
1.The POT series is designed with left helical cutting
face in the cutting flutes, which allows chips exhaust
forward without jamming problem.
2.The sharp cutting performance produces consistent
female threads and is excellent for deep hole tapping.
3.Chamfer length is 4 threads.
