Where this series is used
For medium-soft to medium-hard formations, balancing penetration rate and cutting life.
Tricone bits are classified by IADC code: the first digit (4–8) indicates formation hardness from soft to extremely hard, the last two describe cutting structure and bearing design. Several IADC options are available in each size; selection depends on rock type, abrasiveness and rig parameters.
