Multi-tooth thread taps (commonly known as multi-thread thread taps) What are the characteristics?

         Multi-thread thread tapping, also known as multi-mouth tapping (two or more than the mouth), common with double-pointed or three-tooth mouth, that is, taps lead (wire attack) has two entrances or three entrances, I

They are often referred to as double-tooth or three-tooth mouth, explained in a professional language:

　　 Threaded wire lead to 2 times the pitch forward, called the 2-wire thread tapping, to 3 times the pitch forward, called the 3-thread thread. The so-called 1-thread starting point has 1, 2-thread thread starting point 2, 3-thread thread starting point 3, and so on……。

　    If we rotate the thread along the threaded thread of the thread, the 1-thread thread rotates one turn forward and rotates along the 2-thread thread.

Distance, along the 3-wire thread groove rotation, the rotation will move forward three pitch.

       In short, 1 thread on the circumference of only one thread groove, three thread thread is cut out of three thread groove, rotating a circle is to advance three pitch. Multi-thread thread taps like this, there are

The respective thread groove. This thread taps customary we call the multi-thread thread taps or multi-tooth tapping.

     Popular argument is: first-line thread (a tooth mouth) is the screw rotation of a circle, to advance a distance from the teeth, more than a tooth thread rotation in a circle, the distance from the distance between the teeth, and so on.

      Multi-tooth mouth tapping the use of multi-tooth mouth tapping, the production of multi-tooth screw, the need for more teeth roll roller or tooth plate.
