E Series core cutters are designed to provide the manual cutting process as simple as possible, with improvements in cutting techonology and safety. Operation is easy: the operator feeds the parent core in the machine, setting the cutting length and support rollers according the diameter and wall thickness of the tube. When the core is in the end stop (mechanical target), the operator turn on the machine by pushing the start button, or footswitch (optional), and bring down the knife arm, making the cut and starting a new cycle.
