In the highly specialized field of mechanized rock excavation, the Raise Boring Machine (RBM) represents a massive capital investment. The efficiency of an RBM hinges entirely on the performance of the cutting tools mounted on the reamer head. Among these, the solid tungsten carbide roller cone cutter is the primary interface between the machine and the rock mass.
