General information
Features and applications
GN 123 sheet metal punch is a tool to execute door locks in locker doors made of 2 mm sheet steel.
Before using the sheet metal punch, make a "d" hole according to the dimensions in the table, where a threaded pivot pin is inserted. Install the punch on its end and fit the counternut to lock it.
By turning the big hexagon nut on the opposite end, the puncher is activated and a punch on the metal sheet is produced.
Using a ball bearing located between the die and the hexagon nut allows to apply higher clamping force/torque, minimising friction between the nut and the die.
