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, etc.), Hole opener (Diameter, size of pilot hole, hardness of rocks, thread connection), and Roller cutters. Photos are also helpful. Additional info like drilling depth, rock hardness, drill rig capacity, application type, Incoterm (FOB, CIF, CFR), transport mode, and destination port will ensure a more accurate quote.

Q:What are the lead time and payment terms?

We keep regular models in stock for prompt delivery. Mass production lead time depends on order quantity. We accept standard payment terms including L/C, T/T, D/P, and PayPal. Peak and off-peak season lead times are both within 15 workdays.

Q:What is the material composition of the bit?

The bit is made of High Carbon Steel with tungsten carbide inserts and inlaid friction-reducing alloy. It features hardfaced thrust faces with wear-resistant alloy.

Q:What are the recommended drilling parameters for IADC 117?

For IADC 117, the recommended WOB is 0.30-0.753 kn/mm and RPM is 180-60. This code is designed for very soft formations with low compressive strength and high drillability, such as clay, mudstone, and chalk.

Q:What types of bearings does the bit use?

The bit utilizes advanced metal sealed bearings and rubber sealed bearings to ensure reliability and longevity during drilling operations.
