The letter punch has a base plate (1) which forms the punching die, is provided with an edge strip (3) which is bent downwards and to which a support (2) which supports the bearings (10) for the pressure lever and is provided with the piercing punch guides (17, 18) is attached. This attachment occurs at least partially by means of bent down tangs (20) which are formed by notches (19) cut into the material of the support (2). So that the stability of the support is impaired as little as possible by the cut notches (19), the base plate (1) has perforations (21) in its central horizontal zone. The tangs (20) are formed from notches (19) arranged in the central area (6) of the support (2) matching the perforations (21) in the base plate (1), are pushed through the perforations (21) and are bent over. The part of the support (2) which forms the side cheeks (8) is connected to the central area (6) of the support (2) by means of a continuous edge (7). <IMAGE>
