IADC Specification

First Digit(1~8):

-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(1~4):

-1,2,3, and 4 are further breakdown of formation with 1 being the softest and 4 the hardest .

Third Digit(1~7):

This digit will classify the bit according to bearing/seal type-see information on different bearing types-and special guage wear protection as follows:

-1. Standard open bearing roller bit.

-2. Standard open bearing roller bit,air-cooled.

-3. Standard open bearing roller bit with gauge protection which is defined as carbide inserts in the heel of the cone.

-4. Sealed roller bearing bit.

-5. Sealed roller bearing bit with gauge protection on heel of cones.

-6. Journal sealed bearing bit.

-7. Journal sealed bearing bit with gauge protection on heel of cones.
