The IADC Roller-Cone Bit Classification Method is an industry-wide standard for the description of milled-tooth and insert-type roller-cone bits.
This coding system is based on key design- and application-related criteria.
The currently used version was introduced in 1992 and incorporates criteria cooperatively developed by drill bit manufacturers under the auspices of the Society of Petroleum Engineers.
The IADC classification system is a four-character design- and application-related code.
The first three characters are always numeric;
the last character is always alphabetic.
The first digit refers to bit series, the second to bit type, the third to bearings and gauge arrangement, and the fourth (alphabetic) character to bit features.
