The apex filament attacks N-PO and HC-POIt is mainly used for thread cutting of all kinds of through hole materials. The end wire tapping has the same straight groove as the general hand tapping, but there is a specially designed spiral groove at the front of the cutting part to rotate the pushing chip out of the hole. Because the tip wire has the function of rotating the chip, it can not only keep the groove clean and reduce the resistance during cutting, but also avoid the damage caused by chip jam. Therefore, the end wire tapping can be used to cut the high precision thread faster than the ordinary hand tapping.

HC-POThe cutting groove with 35 degrees is suitable for the threading of various materials, such as medium carbon steel.

N-POA cutting groove with 40 degrees is suitable for viscous materials such as copper, aluminum and medium carbon steel.
