Product Features:

1. IADC 637G Classification for Harder Formations

The IADC 637G code indicates this bit is built for medium-hard to hard formations with highly abrasive characteristics. Ideal formations include:

• Limestone

• Dolomite

• Sandstone

• Chert

These formations are known for their strength and resistance, demanding a rugged and dependable bit to ensure penetration without excessive wear.

2. High-Efficiency Rubber Sealed Bearings

The bit uses rubber sealed bearings to enhance longevity and operational reliability. This bearing system protects internal components from mud, cuttings, and high-pressure fluids, while maintaining lubrication and reducing friction. The result is smooth performance and extended service life under high-stress drilling conditions.

3. Compact, Lightweight Design

At just 27kg, the 171mm tricone bit is a lightweight option for slim-hole and directional drilling operations. It offers excellent maneuverability and is ideal for applications requiring high precision and minimal borehole deviation.

4. Advanced Gauge Protection

Gauge wear is one of the most common causes of bit failure. This tricone bit features reinforced gauge protection to combat side-wall erosion, helping maintain borehole diameter and improving bit longevity. This is especially important in abrasive formations where edge integrity is critical.

5. Optimized Drilling Parameters

With a recommended WOB of 0.70–1.20 KN/mm and RPM of 70–40, this bit allows for fine-tuned operation in varied downhole environments. These parameters help balance penetration rate with durability, minimizing bit wear and reducing operational costs.

6. API-Compatible Threading

The 3 1/2″ API Reg pin ensures universal compatibility with a wide range of drilling rigs and tools. This standard threading makes installation and tool changes quick and safe, streamlining the drilling process.
