Tap is a multifunctional tool that can be used for machining threaded holes and various other purposes. The following are the main uses of taps:
1. Processing threaded holes: The tap can process threaded holes through its own cutting blade, suitable for various fields such as machinery, automotive, aviation, etc.
2. Repair damaged threaded holes: If the thread is damaged or worn during the installation or removal process of the threaded hole, a tap can be used for repair.
3. Making threaded joints: Taps can be used to make threaded joints and can be applied in fields such as mechanical engineering, automotive engineering, and aviation engineering.
4. Cutting grooves with moderate depth: By adjusting the depth of the tap, it can be used to cut grooves with moderate depth, suitable for component processing.
Tap is a tool for processing internal threads, which can be divided into spiral groove tap, edge angle tap, straight groove tap, and pipe thread tap according to their shape. According to their usage environment, they can be divided into manual tap and machine tap, and according to their specifications, they can be divided into metric, American, and imperial tap. Tap is the most mainstream machining tool used by manufacturing operators when tapping.
