Bottom Tap
Taps and dies are tools used to create screw threads, which is called threading. Many are cutting tools; others are forming tools. A tap is used to cut or form the female portion of the mating pair (e.g. a nut). A die is used to cut or form the male portion of the mating pair (e.g. a bolt). The process of cutting or forming threads using a tap is called tapping, whereas the process using a die is called threading.
Known at “bottom taps” or “bottoming taps”, these taps have a 1 to 2 thread chamfer to produce threads in a closed hole, or close to the bottom of a hole.
