JapanOSGApex wire tapping in the through hole tapping into a coil steel system on chip cut material effect. Tooth tapping is difficult for chip clogging. The front edge of the slot of the tip of the wire for special chamber blade groove, so the cutting precision is stable, easy, more resistant transformation layer make the wire tapping.
The tip of the wire tapping is mainly divided into: special wire for ordinary apex screw tap, screw tap, stainless steel with titanium apex apex, apex screw tapping oxidation for different materials and of long stem apex wire tapping, tapping apex accuracy increase. Non standard can be customized!
Features: it is mainly used for thread cutting of various 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.
