Where this series is used

For hard and abrasive formations: granite, limestone, sandy sandstone, dolomite and chert.

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.
