The 9 7/8 inches 250mm IADC CODE 537 Tricone Insert Drill Bit vertical well drill bit is a widely applied rotary drilling tool manufactured to API Spec 7-1 standard. Equipped with pressed tungsten carbide inserts, it relies on impact and crushing force to break rock. It is the preferred bit for soft to medium formation , highly abrasive formations.
