Three pieces of single cone roller bit could build one piece of Tri-cone bit, one piece of Tri-cone bit could be connected with drill pipes to drill oil, gas, water, geothermal and many other sources underground. In construction and infrastructure, single cone roller bit is widely used in rock drilling field mainly including trenchless and rock piling bucket drilling. The traditional Single cone roller bits includes Cone 1 , Cone 2 , Cone 3 , and we also developed the full covered tungsten carbide inserts single cone roller bits to fit more inserts on one cone to get longer working life.
