When a print changes or a line is down, waiting 6-12 weeks isn’t an option. Greenline turns your approved design into a USA-manufactured, low-volume special insert and ships in 5 business days, at no additional cost.
At order entry, our system compares your order details (tool family, geometry, coating, quantity) against the Greenline criteria. Eligible orders are then produced and shipped at unmatched speed and the quality you expect from Horn USA, so you can plan production with confidence.
Greenline provides a broader scope than typical “express” programs, delivering low-volume special inserts across grooving, parting, slotting, and form applications with common PVD coatings and coolant-through options available on qualifying designs. That means you aren’t limited to a narrow set of geometries; you get the right tool fast and accelerate your success.
