Ball Bearing Used when there is a high tolerance between the male and female to prevent contact. Also, used for long run dies.
Standard Used when a lower tolerance between the male and female is not required and the run is shorter.

Die Life The amount of vertical shape the die has. The greater the die life, the longer distance the slug has to travel before exiting.

Die Shoes:
