A tap cuts or forms a thread on the inside surface of a hole, creating a female surface which functions like a nut.
A die cuts an external thread on cylindrical material, such as a rod, which creates a male threaded piece which functions like a bolt.
Twist drill is a rotating cutting tool, used for cutting holes in rigid materials.
End mills are tools which have cutting teeth at one end, as well as on the sides, they are used for a variety of things including facing an edge and cutting slots or channels. A drill bit can only cut in the axial direction, but a milling bit can generally cut in all directions.

Tool used in cutting an external thread
The correct answer for the tool used in cutting an external thread is option 'C', which is a Die.
Explanation:
- Thread cutting: Thread cutting is a process used to create threads on the external surface of a cylindrical workpiece. It involves removing material from the workpiece to form the desired thread profile.
- External thread: An external thread is a thread that is cut on the outside surface of a cylindrical workpiece. It is commonly used for fastening purposes, such as screwing a bolt into a nut.
- Die: A die is a specialized cutting tool used in the process of thread cutting. It is a cylindrical or rectangular block with a threaded hole in the center. The threaded hole matches the desired thread profile, and the die is used to cut the external thread on the workpiece.
- Operation: The die is typically held in a die holder or a die stock, which provides the necessary stability and leverage for the cutting process. The workpiece is rotated while the die is applied against its external surface. As the die is turned, it gradually cuts into the workpiece, removing material and forming the thread.
- Types of dies: There are different types of dies available for cutting external threads, including solid dies, adjustable dies, and split dies.
- Solid dies: Solid dies are one-piece dies with a fixed thread size. They are commonly used for mass production or repetitive threading operations.
- Adjustable dies: Adjustable dies have a split design that allows for adjustment of the thread size. They are versatile and can be used for a wide range of thread sizes.
- Split dies: Split dies consist of two halves that can be adjusted to accommodate different thread sizes. They are commonly used for threading pipes and other cylindrical workpieces.
- Application: Dies are widely used in various industries, including manufacturing, automotive, plumbing, and construction. They are essential tools for creating external threads on bolts, screws, pipes, and other threaded components.
In conclusion, a die is the correct tool used in cutting an external thread. It is a specialized cutting tool with a threaded hole that matches the desired thread profile. The die is applied against the external surface of the workpiece and rotated to cut the thread. Different types of dies are available to accommodate various thread sizes and applications.
