Frequently Asked Questions
What is the minimum order quantity (MOQ) for carbide rod blanks?
There is no strict MOQ — we accept sample orders of 1–5 pieces for qualification testing. Standard bulk orders typically start from 10–50kg depending on diameter and grade. Contact us with your specifications for an exact MOQ and pricing breakdown.
What is the lead time for tungsten carbide rods?
Sample orders ship within 3–5 business days. Standard bulk orders for diameters under 16mm are ready within 2–3 weeks; diameters above 16mm require 3–4 weeks. We can confirm exact lead time at the time of order placement.
What payment terms do you accept?
We accept T/T (bank transfer), L/C (letter of credit) for large orders, and Western Union. Standard terms are 30% deposit with order, 70% balance before shipment. Long-term customers may qualify for net payment terms.
Can you provide material test reports for carbide rods?
Yes. Every shipment includes a material test report covering HRA hardness, density, TRS (transverse rupture strength), and grain structure. Third-party inspection is also available on request.
Do you supply carbide rods with coolant holes?
Yes. We manufacture carbide rods with straight coolant holes and helical coolant holes (30°, 40°, and custom helix angles). Specify hole diameter, position, and helix angle when requesting a quote.
