Description
TCI Tricone Drill Bit for Rock Drilling
TCI Tricone Drill Bit uses high-strength tungsten carbide inserts mounted in three rotating cones to provide efficient rock crushing, strong wear resistance and reliable rotary drilling performance.
Different IADC codes, insert shapes, bearing structures and gauge protection options are available to match formations ranging from soft and highly drillable rock to medium-hard and abrasive formations.

Reliable rock crushing for rotary drilling
Six design advantages behind the TCI Tricone Drill Bit.
01 / 06 Tungsten Carbide Insert Cutting StructureHigh-quality tungsten carbide inserts improve wear resistance and maintain stable cutting performance in abrasive formations. | 02 / 06 Three-Cone Rock CrushingThree rotating cones crush the formation through rolling and impact action, providing efficient rotary drilling. | 03 / 06 Multiple IADC ConfigurationsDifferent IADC codes are available to match soft, medium and hard formations. |
04 / 06 Reinforced Gauge ProtectionGauge inserts and hardfacing can improve gauge holding capability and reduce outer-diameter wear. | 05 / 06 High-Precision Bearing StructureJournal bearing designs can improve cone stability and bearing life under high drilling loads. | 06 / 06 Reliable Sealing & LubricationSealed bearing structures and lubrication systems help protect internal components from drilling debris and contamination. |
Used across mining, water well and oilfield drilling
TCI tricone drill bits are commonly used for mining drilling, water well drilling, oil and gas drilling and quarry drilling. Other applications include blast hole drilling, geothermal drilling, foundation drilling, reverse circulation drilling and construction drilling.
01 Mining DrillingReliable drilling for mining, blast hole and quarry production projects. | 02 Water Well DrillingEfficient rotary drilling for water well projects in varied formations. |
03 Oil & Gas DrillingSuited to oilfield rotary drilling where TCI wear resistance is required. | 04 Quarry DrillingStable rotary performance for quarry and rock extraction projects. |
Suitable Rock Formations by IADC⚠️ Note: The final IADC code and bit configuration should be selected according to formation hardness, abrasiveness, compressive strength and drilling parameters. |
Recommended IADC codes and drilling parameters
The table below lists recommended IADC codes, formation types and typical drilling parameters. Actual parameters should be adjusted according to rig capability and formation response.
Tungsten carbide insert shapes
High-quality tungsten carbide inserts are used to improve overall mechanical performance and wear resistance. Different insert shapes can be selected according to formation conditions.
Conical Inserts Suitable for soft to medium formations where efficient penetration is required. | Chisel Inserts Provide aggressive cutting for soft to medium-hard formations. | Spherical / Hemispherical Designed for harder formations requiring impact resistance and wear resistance. | Customized Profiles Custom insert profiles available for specific formation requirements. |
Maintain borehole diameter and extend bit life
Multiple gauge protection methods can be used to help maintain borehole diameter and extend bit life in abrasive formations.
Gauge Carbide Inserts Carbide inserts placed on the gauge row help resist outer-diameter wear. | Heel-Row Gauge Protection Heel-row inserts provide additional gauge protection during rotation. |
Shirttail Hardfacing Hardfacing applied to the shirttail helps reduce wear in abrasive formations. | Reinforced Outer Gauge Structure Reinforced outer structure improves gauge holding capability under demanding drilling loads. |
High-precision journal bearing options
High-precision journal bearing structures can be selected for demanding drilling conditions. Typical features improve abrasion resistance and reduce seizure risk under heavy rotary drilling loads.
Dual Thrust Surfaces Dual thrust surfaces help distribute axial loads during rotation. | Cone Locking System Cone locking design helps maintain cone positioning under drilling loads. | Hardfaced Bearing Surfaces Hardfaced surfaces improve abrasion resistance and bearing life. |
Friction-Reducing Alloy Friction-reducing alloys help reduce heat and wear in bearing interfaces. | Silver-Plated Interfaces Silver-plated bearing interfaces help reduce friction and improve durability. | Application These features improve abrasion resistance and reduce seizure risk under heavy rotary loads. |
Protect the bearing system from drilling debris
Available sealed configurations can protect internal components from drilling fluid and abrasive cuttings.
HNBR O-Ring Sealing HNBR sealing material provides good resistance to drilling fluids and high temperatures. | Optimized Seal Compression Controlled seal compression helps maintain reliable sealing performance. |
Pressure Compensation Pressure compensation helps balance internal and external pressure in deep drilling. | High-Performance Grease High-performance grease lubrication helps protect bearings from heat and wear. |
