Packaging & Delivery
Inner Protection
All carbide drills, indexable inserts and tool parts are fixed into pre-cut high-density foam slots, effectively avoiding collision, scratch and shifting during long-distance sea/air transportation; foam cushions absorb vibration for full product surface protection.
Outer Packaging
Sturdy corrugated kraft carton features good compression & moisture resistance, ideal for international export logistics. A clear product label is pasted outside the box to mark contents as Metal Cutting Tools for easy customs clearance and stock management.
Packing Advantage
Separated compartment layout sorts different drill models & accessories neatly, convenient for customers to check items upon receipt. All packages comply with standard export packaging requirements for global shipment.
