Product Q&A

Q:How to get an exact quotation?

Please send detailed information including Tricone bits (Diameter, IADC code), PDC bits (Matrix or Steel body, blades quantity, cutter size), Hole opener (Diameter, pilot hole size, rock hardness, thread connection), and Roller cutters (Diameter of cones, model number). Sending photos is also a simple way. Additional info like drilling depth, HDD length, rock hardness, rig capacity, application type, Incoterm (FOB/CIF/CFR), transport method, and destination port will ensure a more exact quotatio

Q:What are the lead time and payment terms?

Regular models are available in stock for prompt delivery. Mass production lead time depends on order quantity. We accept all regular payment terms including L/C, T/T, D/P, and PayPal. Transportation from our factory to Beijing or Tianjin takes only one day, ensuring fast and economical inland charges.

Q:What materials are used for the drill bits?

The bits are made of High Carbon Steel with tungsten carbide inserts and inlaid friction-reducing alloy. Thrust faces are hardfaced with wear-resistant alloy.

Q:What are the recommended drilling parameters?

Parameters vary by IADC code and formation. For example, IADC 117 requires 0.30-0.753 kn/mm WOB and 180-60 RPM for very soft formations. IADC 637 requires 0.5-1.2 kn/mm WOB and 80-40 RPM for hard to very hard formations. Please refer to the specific table for each code.

Q:Do you offer OEM and ODM services?

Yes, we offer both OEM and ODM services for our drilling tools.
