A tap is used to cut the female portion of the mating pair (e.g., a nut). A die is used to cut the male portion of the mating pair (e.g., a screw). The process of cutting threads using a tap is called tapping, whereas the process using a die is called threading. Both tools can be used to clean up a thread, which is called chasing. ²Î¿¼£ºhttp://en.wikipedia.org/wiki/Tap_and_die http://www.chinabaike.com/english/en/684772.html |
