Round and Hexagon Dies
Round or hexagon cutting dies are used to manufacture bolt threads; such threads are used for simple screws, for example. Compared to the conventional process techniques of chasing, whirling, and turning with corresponding thread cutting inserts, cutting dies have decisive advantages when cutting threads: Incremental feeding is not necessary, and the result is always a thread that is true to gauge – provided that the cutting geometry is properly designed for the material to be cut.
Cutting dies are also used when thread flanks rough from use need to be smoothened or when threads need to be cleaned.
