Tap And Die

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.

Famous quotes containing the words tap and/or die:
“A book is like a man—clever and dull, brave and cowardly, beautiful and ugly. For every flowering thought there will be a page like a wet and mangy mongrel, and for every looping flight a tap on the wing and a reminder that wax cannot hold the feathers firm too near the sun.”
—John Steinbeck (1902–1968)
“I ... hate with a murderous hatred those men who, having lived their youth, would send into war other youth, not lived, unfulfilled, to fight and die for them; the pride and cowardice of those old men, making their wars that boys must die.”
—Mary Roberts Rinehart (1876–1958)
