Abstract:
The present invention relates to a die comprising a die core (10) of a hard material and at least two pre-stressed rings (60, 70) of increasing diameter placed around the die core and methods of making and using the same. The die core (10) is held in place by a force generated through deformation of mating geometric features on the die and the rings (60, 70) of increasing diameter.
