Abstract
A punch assembly for a turret punch press having a two piece reciprocally movable punch member that has a punch point insert removably attached to a punch driver that allows replacement of the punch point insert without the need to extract the punch member from its punch guide. A locking assembly having four vertical guideways containing slider strips for coupling the punch point insert to the punch driver ensures precision registration of the punch point insert with its driver.
