Tricone Drill Bits


Roschen offers a complete line of tricone drill bits. Tricone bits are available in new and used (re-tip and re-run) steel tooth and tungsten carbide insert, in sizes from 2 1/2" to 36", for use in all formations, with any bearing/seal type, and with a wide range of additional custom features.

New Tricone Drill Bits

Roschen offers new steel tooth and tungsten carbide insert (tci) tricone bits in sizes from 2 1/2" - 36", with open or sealed bearings, regular or jet circulation, and a wide range of additional custom features for ideal performance in any formation. Tricone bits can be customized to optimize penetration rates and bit life in particular formations and under specific operating weights and rotation speeds.
Steel teeth or carbide inserts come in a variety of shapes, sizes, and grades of tungsten carbides to address specific drilling conditions. TCI bits offer increased durability over steel tooth bits but also carry a higher cost.


Open bearing bits feature bearings without a seal that are open to outside debris. Open bearing bits are generally cheaper than sealed bearing bits, and recommended for shallower holes. Sealed bearing tricone bits are available for use in applications where, historically, bearing life has limited bit performance. Sealed roller bearing bits extend the bearing life, allowing for increased utilization of the cutting structure.

IADC Codes - Tricone Rock Bits

IADC Codes are designed to make it easier for drillers to describe what kind of rock bit they are looking for to the supplier.
The first three digits classify the bit according to the formation it is designed to drill and the bearing/seal design used.
