A interrupted -shaped tap is a type of tap for tapered threads, in which the peak of the complete tap thread is removed so that it jumps into a single peak.
Tapered taps for pipes perform thin cutting even in fully threaded parts.
By reducing the number of threads in the thinly cut part, the interrupted type has the role of suppressing the instability of the cutting force during machining, chamfer each mountain firmly .
It is especially effective for raw materials and stainless steel, which are soft and easily resistant.
