Our Sub-Min-D is one of the specialists belonging to the Alfra-hole puncher family. The core competency: Punching out openings for 9-up to 50 pin connectors. Special anti-rotating axes are serving as a tension bolt for puch and die. Like all ALFRA suare- or rectangular punchers, the Sum-Min-D is equipped with a sideways puncher part ejection, to avoid the tilting of the waste piece in the die.
