A roller bit is a rock drilling tool widely used in piling, foundation drilling, and core barrel applications.
Roller bit core barrel systems are widely used in hard rock piling and deep foundation drilling projects. Compared with traditional bullet teeth core barrels, roller bit core barrels provide stronger rock crushing capability and better performance in high compressive strength formations.
Best for the less chanlleging hard rock formation.
