Hand Taps are tough screw-like tools that are used to cut threads into nuts
or holes. They have squared off ends with distinct series of grooves along their lengths that can cut new threads or repair damaged ones. The hand taps are used after an appropriate size hole has been drilled into the desired material.
There are three types of hand taps, namely, Taper, Plug, and Bottoming taps. Hand tapping operations are usually initiated using the Taper Tap because its first 8 to 10 threads are tapered. This makes it easier to create new threads in virgin material. The tapered threads create lead grooves that can become more defined as the tap goes deeper. Tapered plugs are used in applications that need shallow threads.
Plug Taps have 3 to 5 tapered threads and are harder to use on virgin holes than the tapered taps. They are used in applications that need deeper threads. Finally, bottoming taps are used together with Taper or Plug Taps. Bottoming Taps only have one or two tapered threads and are used to deepen the threads made using Taper or Plug Taps.
