摘要：
A punch assembly for a turret-type punch press comprises an outer guide sleeve having an inner bore in which a punch shank fits for reciprocating but not rotating movement. The punch shank has a concentric, downward opening formed in a lower end in which is received a head portion of an insert that has a punch point formed on it. Built into the shank is a latching mechanism for releasably wedging and thereby securing the insert to the lower end of the shank.
