Roller bits
Roller bits are high-performance HDD drilling tools designed for pilot hole drilling and hole enlargement in hard and abrasive formations. These bits feature rotating cones with tungsten carbide or diamond inserts, enabling efficient rock penetration with reduced wear. Commonly used in oil & gas, water, and utility installations, roller bits deliver high-speed drilling and exceptional durability in challenging geological conditions.
Key Features
- Rotating Cone Design – Reduces friction and improves cutting efficiency.
- Tungsten Carbide or PDC Inserts – Maximizes durability and wear resistance.
- Optimized Bearing System – Ensures smooth rotation and longer lifespan.
- Sealed or Open Bearing Options – Adaptability for various drilling conditions.
- High-Torque and High-Impact Resistance – Handles extreme HDD applications.
- Available in Various Sizes – Custom diameters for different borehole requirements.
Types of Roller Bits
- Mill Tooth Roller Bits – For softer rock formations, featuring steel teeth for aggressive cutting.
- Tungsten Carbide Insert (TCI) Roller Bits – Ideal for hard rock drilling with superior wear resistance.
- Hybrid Roller Bits – Combine PDC and roller cones for maximum drilling efficiency.
- Sealed Bearing Bits – Designed for extended use in abrasive environments.
