ROLLER CONE BIT CUTTING STRUCTURE
Soft formation bits require deep penetration into the rock so the teeth are long, thin and widely spaced to prevent bit balling.
Bit balling occurs when soft formations are drilled and the soft material accumulates on the surface of the bit preventing the teeth from penetrating the rock.
The long teeth take up space, so the bearing size must be reduced. This is acceptable since the loading should not be excessive in soft formations.
