Key Features:

1. Large Size for High-Capacity Operations

With a size of 30 inches (762mm), this tricone bit is tailored for large-diameter drilling applications. It’s well-suited for oil, gas, and geothermal projects that require wide boreholes, offering high drilling performance and extended service life.

2. IADC537 Classification

This bit follows the IADC537 code, which is designed for medium-hard formations with intermittent hard streaks. It balances bit toughness with cutting aggression, ideal for challenging formations where compressive strength and abrasiveness are prevalent.

3. TCI Cutting Structure

The Tungsten Carbide Inserts (TCI) ensure improved wear resistance and longer bit life. The inserts are engineered for deep penetration and high-speed rotation, even in the presence of abrasive rock layers and stringers. The bit is ideal for formations like hard shale, hard sandstone, and dense limestone.

Construction and Design

4. Bearing Type

This tricone bit incorporates a rubber sealed bearing system, designed to minimize wear and heat during high-speed drilling. The seal maintains a consistent lubrication level, reducing the risk of bearing failure under extreme operational conditions.

5. Gauge Protection

Equipped with gauge protection to enhance durability and maintain hole diameter throughout the bit’s service life. This feature prevents the bit from excessive wear and improves reusability.

6. Thread Connection

The bit comes with an 8 5/8″ API Reg pin connection, a standard and robust interface that ensures secure mounting on the drill string. This connection supports heavy torque and provides a reliable linkage in deep drilling operations.

Operating Parameters

7. Weight on Bit (WOB)

This tricone roller bit operates best with a Weight on Bit (WOB) between 0.35–1.05 KN/mm, which allows the bit to exert optimal force on the formation without compromising its structural integrity.

8. Rotational Speed (RPM)

The recommended RPM ranges from 110 to 40 r/min, depending on the formation hardness and drilling strategy. Lower RPM with higher WOB is suitable for harder rocks, while higher RPM is effective in softer layers.

Formation Suitability

This bit is engineered for medium hard formations with high compressive strength and stringers, such as:

• Hard shale

• Sandstone

• Limestone

Its durability, penetration efficiency, and resistance to impact make it a reliable choice for both exploratory and production drilling.

---
