CONCENTRIC ROLLER BIT CORE BARREL

Core barrels with roller bits are drilling tools used for coring through rock shelves, especially for strong rock or rock with deep cracks.
RB-CB not only can improve the penetration rate, but also reduced drilling chatter and the strain on drilling rigs, compared to core barrels with bullet teeth/Round shank cutters.
The new formula and the new process of high-quality tungsten carbide teeth improve the service life of the reaming drill.

When selecting a core barrel with roller bits, you can consider factors such as:

  • Drilling surface hardness: How hard is the surface you're drilling into?
  • Core sample diameter: What size core sample do you need?
  • Drilling depth: How deep do you need to drill?
  • Compatibility: Will the core barrel work with your existing drilling equipment?
