Rectangular Dies

Flat and Rectangular Die Holders

Dove tail or t-bolt slot die holders are available for mounting rectangular dies into roll marking or press marking machines.


GT SCHMIDT offers solid engraved lettering knurls, a basic round die used in roll marking machines, or lathes. They may be engraved with part numbers, trademark, company name or other legend.

Solid lettering knurls require a knurl support carriage.

Round Dies

Lettering Knurl support carriage

Knurl support carriages are designed to hold and support round type holders and solid lettering knurls. The carriage is mounted to the machine die slide for roll marking flat parts. Several sizes are available in stock in both t-slot and dovetail mounts.
