Cone bits are the most widely used in oil drilling and geological
drilling. The roller cone bit has the functions of impacting,
crushing and shearing the formation rock when rotating, so the
roller cone bit can adapt to various soft, medium and hard
formations. Especially after the emergence of jet roller cone bits
and long nozzle roller cone bits, the drilling speed of roller cone
bits has greatly increased, which is a major revolution in the
history of roller cone bits. Among them, Tri-cone Drilling Tools
are widely used all over the world.
