Thread former DIN 371-D

The forming tap consists of cobalt alloyed, nitrated and vaporised heavy-duty high-speed steel. Applications: for non-alloyed and alloyed steels up to a strength of 1000 N/mm² and non-ferrous metals. As shaping is done without cutting, no interruption of the course of the fibre in the material. The deformation creates very rigid threads. Consistent accuracy even with high productivity.
