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. For more accuracy, provide drilling depth, drilling length, rock hardness, drill rig capacity, application type, Incoterm (FOB, CIF, CFR), transport method, and destination port.

Q:What are the lead time and payment terms?

We always have regular models 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. Peak and off-peak season lead times are both within 15 workdays.

Q:What are the available bit sizes?

Available bit sizes include 7 1/2'', 8 1/2'', 9 7/8'', and 12 1/4''.

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 is suitable for very soft formations with low compressive strength and high drillability, such as clay, mudstone, and chalk.

Q:What is the material composition of the bit?

The bit is made of tungsten carbide inserts with inlaid friction-reducing alloy. The body material is High Carbon Steel.
