ABSTRACT:
A coiling point holder for a spring making machine precisely fixes the angular and axial position of the coiling point relative to the holder and allows for the pre-established coiling point positions to be replicated upon reversing or replacing the coiling point. The angular position of the coiling point is fixed by a diametral slot of an insert which is angularly fixed in the holder.
