Under the action of drilling pressure and drill string rotation, the tricone bit crush and eat into the rock, and at the same time produce a certain sliding and shearing rock. When the cone rolls at the bottom of the well, the teeth on the cone impact and press into the formation in turn. This action can crush a part of the rock at the bottom of the well. At the same time, the shearing action brought by the sliding of the cone cuts off the remaining part of the rock between the teeth, making the rock at the bottom of the well completely crushed and the hole extended.

The tricone bit is the most widely used tool in petroleum drilling and geological drilling. Rotary bit has the function of impacting, crushing and shearing rock in formation, so it can adapt to soft, medium and hard formation. Especially after the emergence of jet cone bit and long nozzle cone bit, the drilling speed of cone bit has been greatly improved, which is a major revolution in the development history of tricone drill bit. The tricone bits can be divided into milling (steel teeth) cone bits, inlaid (carbide teeth on the cone) cone bits and single cone, double cone, three cone and multi cone bits according to the number of cones. Tricone bit is the most widely used bit at home and abroad. 


ROSHCHEN always focus on high quality and good service, we try our best to meet all customer’s needs, we sell our products to many countries include China.


As the tricone bits, We have classified the bits based on their diameter (footprint), The IADC number further classifies the tricone bits based on the tooth material of construction, suitability for drilling into soft, medium or hard rock and bearing type used.  We can supply bits for all possible combinations of IADC number.
