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.
We 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.
