A tap and die set is a collection of tools used for cutting threads, both internally and externally, in various materials such as metal, wood, or plastic. These sets typically include taps for creating internal threads and dies for creating external threads.
- Taps:
- Taps are cutting tools used to create internal threads in pre-drilled holes. They come in different shapes and sizes to match the desired thread specifications.
- There are three main types of taps: taper, plug, and bottoming. Taper taps have a gradual cutting profile and are used to start threads. Plug taps have a slightly shorter chamfer and are used for through holes. Bottoming taps have a very short chamfer and are used to cut threads to the bottom of blind holes.
- Dies:
- Dies are cutting tools used to create external threads on cylindrical workpieces. They are typically used with a die stock or die handle for holding and rotating them.
- Like taps, dies come in various sizes and shapes to match the desired thread specifications. They are usually labeled with the thread size and pitch they are designed to cut.
- A tap wrench is a hand tool used to hold and turn taps during the threading process. It provides a firm grip on the tap while allowing for precise control during cutting.
- Die Stock:
- A die stock, also known as a die handle, is a tool used to hold round dies for cutting external threads. It typically consists of a handle and adjustable jaws to securely hold the die in place while it is rotated.
- Some tap and die sets include a thread gauge, which is a measuring tool used to verify the pitch and diameter of threaded holes or bolts. It helps ensure that the correct tap or die is selected for the desired thread size.
Overall, a tap and die set is a versatile tool kit essential for creating threaded connections in various applications, from automotive repair to metalworking and beyond.
