2. 大致上被加工材之切削性良好，攻牙長度較短及切削油充分使用之場合，其攻牙速度可 以設在較高 之速度，反之被削性不好或不明瞭等條件時，則攻牙速度可設在下限處，然後再視情況增加較安全。
1. Following usage chart the recommended tapping speeds and cutting fluids, tap material type of tap chamfer length dimension of drill hole work materials and cutting fluids are important factors for determining suitable tapping speed.
2. When work material has excellent workability, when there is a little depth of tapping, or when tapping flud can be sufficieny, select rather high tapping speed. When workability of work material is unknown, it is safe to try nearly the lowest tapping speed at first, and theen increwse the speed gradually.
