Die holders for the largest press dies for each swager are mounted on the respective swager as standard. Starting with the 300T swager optional insert die holders can be mounted permitting the use of smaller press dies.
Example; for a 1000T swager press dies size E or E1 are standard. With the insert die holders VIN D/E LIN the smaller press dies D can be used. If the insert die holders VIN C-C1/D are added even press dies size C and C1 will fit.
