Over the course of Hill Engineering's 50 year history, we have designed and built cutoff dies and systems for the tubing industry as well as the roll forming industry. Besides basic tube cutoff dies, we have built in-line punching and end swaging dies, side-action cutoffs and dimple-free cutoff systems.
