Which types of taps are considered the most common?

Taper, plug, and bottoming taps are the most common types used in threading operations. Each of these taps serves a specific purpose in the creation of internal threads.

Taper taps are designed with a gradual lead and facilitate easier starting of the threading process. They help to guide the tap into the material smoothly, minimizing the risk of misalignment.

Plug taps have a less tapered lead compared to taper taps, allowing for more threads to engage with the material when starting the threading process. They are commonly used for through holes as they can reach deeper into the workpiece.

Bottoming taps, as the name implies, are used to create threads all the way to the bottom of a blind hole. They have little taper at the start, allowing them to form threads very close to the bottom of the hole.

Together, these taps cover a broad range of threading applications, making them indispensable tools in pipe fitting and other machining processes. This versatility and functionality are why these tap types are considered the most commonly used in various industries.

The other options do not relate to common tap types used for threading. Square, round, and hex, for example, refer to shapes rather than specific tap designs, while screw, twist, and taper focus on different
