Roller cone bits have conical cutters or cones with steel teeth or tungsten carbide buttons around them. As the drill string is rotated, the bit cones roll along the bottom of the borehole in a circular motion. As they roll, new teeth come in contact with the bottom of the hole, chipping the formation below and around the bit tooth. Air or drilling fluid lift the crushed rock chips from the bottom of the hole and up the annulus. As rotation continues, another tooth makes contact with the bottom of the hole and creates new rock chips, thus, the process is continuous.
Roschen offers a complete line of tricone, bicone and reverse circulation bits. Tricone bits are available in new and used (re-tip and re-run) steel tooth and tungsten carbide insert, sizes from 2 1/2" to 36" for use in all formations, with any bearing/seal type, and a wide range of additional custom features.
To simplify tricone bit selection, Roschen follows the IADC bit classification system. The IADC Code describes a tricone bit, explaining the bit type (steel tooth of tungsten carbide insert), the formation(s) the bit is meant for, and the bearing/seal type.

Bicone bits are roller-cone type bits similar to tricones that have two cones mounted on bearings. Bicone bits are generally recommended for use in small diameter drill holes and soft formations when speed is more of a priority than hole accuracy.
