Three cone chisel 104.8mm tricone rock bit for very hard rocks

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.

Re-Tip Steel Tooth Tricone Drill Bits

Re-tip steel tooth tricone bits are gently used bits that usually come from the oil fields. They are refurbished for use in non-oilfield rotary applications, such as water wells, HDD, and construction type drilling. These bits offer significant cost savings over new bits. ROSCHEN offers a wide range of premium, oil field quality re-tip steel tooth bits in sizes ranging from 2 1/2" to 36". Re-tip bits are available for use in soft, medium, and hard formations.

Re-Run Carbide Insert Tricone Drill Bits

Re-run carbide insert bits are used bits that have been re-worked, cleaned, and often times painted. Re-runs offer significant cost savings over new carbide insert bits. ROSCHEN offers a variety of re-run carbide bits in sizes ranging from 2 1/2" to 36". All re-runs are premium quality and available for use in soft, medium, and hard formations.
