Taps and dies are tools used to create purpose screw threads, which is called threading. Many are cutting tools; others are forming tools. A tap is used to cut or form the female portion of the mating pair (e.g. a nut). A die is used to cut or form the male portion of the mating pair (e.g. a bolt). The process of cutting or forming threads using a tap is called tapping, whereas the process using a die is called threading. The Die for threading purpose is hold in the various Die holder sizes. To hold thread die making out threading. Routine depth is 40 mm and tailor-made depth as required. The size of hole is different in 3 diameters for different machine mode. Both inner and external threading can be done well by one single TAIPU machine, a very useful tapping and threading complete solution. With the die installed, the holder may remain stationary as the material to be cut on the spindle is advanced into the die, or the material to be cut can remain stationary and the die holder is made to rotate in the tailstock. DCP007-48 is a holder of threading die with 48 mm diameter 50 mm routine depth. Tailor-made depth and diameter with details size and drawing.
