If the punch and die are used longer than the specified service life, the die holder will
be subject to excessive stress and may break off.
When a 1/16" (1.6 mm) mild steel trapezoidal plate is cut, wear will be especially quick.
Replace the punch and die as soon as possible after reaching the service life.
