先端丝攻


POT :

一般用於炭素鋼、合金鋼及非鐵金屬,其切屑像線圈狀連續由前方排出,因此沒有切屑障害的問題,適用於貫通孔。

Suitable for through hole tapping of carbon steels, alloy steels, and nonferrous metals, whose chips are produced in continuous coil form, these taps discharge chips through the hole.


TIN-POT :

適用廣泛的被削材,特別是不鏽鋼、調質材等之貫通孔的高速攻牙作業。

This tap is capable of tapping a wide range of materials, but is especially suited for high speed tapping of stainless steels, and quenched and temperea steels.


DH-POT :

適用於攻牙長度較長的貫通孔,而且容易燒著的被削材。

Suitable for tapping deep through holes, especially in materials that are prone to burn seizure during machining.
