A stamping or nibbling machine for cutting pieces off a metal workpiece comprises a hollow punch adapted to be driven against the workpiece to win small pieces thereof. A die having an opening therethrough is adapted to be located in alignment with the punch and on the other side of the workpiece. A centering pin has one end projecting into the interior of the punch and an opposite end extending out of the punch and adapted to engage into the opening beyond the position of the workpiece and a displacing mechanism for the pin is carried within the hollow punch and is advantageously in the form of a coil spring located between a collar at the inner end of the punch and the inner wall of the hollow workpiece which moves the outer end of the centering pin into association with a centering pin mounted within the die below the opening thereof.
