Formtap tool
1/8" - 1" BSP | Formtap Formdrill

Formtaps are special tools for the chip free production of threads inside a hole. The non-cutting cold working process has a extreme compacting effect on the material and does not break the so called fiber direction of the material. In contrast to "cutting" the threads by roll forming the material is not cut out. Instead due to the special geometry of the tool, the material is pushed into the area of the thread flank, the material is consolidated in such a manner that the developing thread can withstand extreme static and dynamic loads.

This procedure is particularly suitable with Thermal Drilled holes to the production of threaded connections. The result is that the structure of the thin-walled socket is very strongly consolidated, whereby a high firmness of the thread is ensured.
