The CTT1 is perfect for processing single-wall corrugated cardboard. This tool accommodates crease wheels with a diameter of 61 mm/2.4” and a width of 20 mm/.8”. Fully supported by the cutting software, the tool produces high-quality creases both with and against the corrugation without tearing or cracking the top layer. The crease wheels simply snap into the holder, making them very easy to insert and replace.
