IADC Codes make it easier for drillers to describe what kind of rock bit they are looking for to the supplier. Bit Brokers International follows the IADC bit classification system in which the first three digits classify the bit according to the formation it is designed to drill and the bearing/seal design used.
First Digit:
1, 2, and 3 designate STEEL TOOTH BITS with 1 for soft, 2 for medium and 3 for hard formations.
4, 5, 6, 7 and 8 designate TUNGSTEN CARBIDE INSERT BITS for varying formation hardness with 4 being the softest and 8 the hardest.
Second Digit:
1, 2, 3 and 4 are further breakdown of formation with 1 being the softest and 4 the hardest.
Third Digit:
This digit will classify the bit according to bearing/seal type - see information on different bearing types - and special guage wear protection as follows:
