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.

“Be not righteous over much; neither make thyself over wise; why shouldest thou destroy thyself? Be not over much wicked, neither be thou foolish: why shouldest thou die before thy time?”
