Frequently Asked Questions
What is a TCI Tricone Bit?
TCI stands for Tungsten Carbide Insert. These bits are designed with high-strength tungsten carbide compacts pressed into the cone, making them ideal for drilling through hard and abrasive rock formations.
What applications are these bits suitable for?
They are highly effective for oil and gas exploration, water well drilling, and mining operations. They work best in formations ranging from soft mudstone and salt beds to hard sandstone and shale.
What does the IADC Code 517 signify?
The IADC code 517 refers to a TCI bit designed for soft to medium formations with low compressive strength. The "5" indicates TCI cutting structure, and "1" indicates the series for soft formations.
What bearing type is used in this drill bit?
This bit features a Rubber O-Ring Sealed Journal Bearing. This design provides excellent durability and protection against drilling fluids, ensuring a longer service life for the bearing.
How do I choose the right connection size?
The connection size depends on your drill string requirements. For example, a 6" bit typically uses a 3 1/2" API Regular pin connection. Refer to our connection size table for standard mappings.
What is the recommended rotary speed and WOB?
For optimal performance, the recommended rotary speed is between 50 to 120 RPM, and the Weight on Bit (WOB) should be maintained between 0.35 to 1.05 KN/MM.
