9-7,8 IADC645 Water Well Drill TCI Rock Roller Tricone Bit Deep Oil and Gas Drilling

The TCI Tricone Bits are designed specifically for medium to hard rock formations, providing efficient drilling capabilities for deep oil and gas exploration. These bits are built with tungsten carbide inserts that ensure maximum durability and performance in challenging geological conditions.

Key Features:

• Aggressive Chisel Tungsten Carbide Inserts: Designed to improve drilling rates and extend the life of the bit, especially for medium rock formations.
• HSN Rubber O-ring: Provides reliable sealing for bearing durability.
• Wear Resistance Tungsten Carbide Inserts: Used in the outer rows of the bit to minimize bit gauge loss, especially in hard and abrasive formations.
• Hemispherical Shaped Inserts: Maximizes cutter durability and ensures long-lasting performance.
• Versatile Application: Ideal for drilling in a variety of formations from very soft to hard rock.
