Various Three Cone Drill Bit
Milled Tooth Three Cone Drill Bit
We supply milled tooth three-cone drill bits, featuring robust steel teeth integrated into the cones. These bits are highly effective for drilling softer to medium-hard, non-abrasive rock formations such as shale, sandstone, and limestone. Their aggressive cutting action ensures high penetration rates, optimizing efficiency in less demanding conditions.
Tungsten Carbide Insert (TCI) Three Cone Drill Bit
We offer TCI three-cone drill bits equipped with durable tungsten carbide inserts. These versatile bits excel in a broad range of formations, from medium to extremely hard and abrasive rocks like granite and quartzite. The inserts provide superior wear resistance, ensuring extended bit life and consistent performance.
Sealed Bearing Three Cone Drill Bit
We provide sealed bearing three-cone drill bits, which incorporate an advanced sealed lubrication system to protect the bearings from drilling fluids and contaminants. This design significantly extends the bit’s operational life, making them ideal for long runs and demanding drilling environments where bit longevity is crucial.
Open Bearing Three Cone Drill Bit
We supply open bearing three-cone drill bits, which use unsealed bearings lubricated by the drilling fluid. These bits are often more cost-effective for applications where bearing life is less critical, such as shallower drilling or in formations that do not generate excessive heat, providing an economical drilling solution.
Journal Bearing Three Cone Drill Bit
We offer journal bearing three-cone drill bits, featuring a robust, friction-based bearing system designed for heavy-duty applications. These bits are known for their high reliability and exceptional ability to withstand significant axial and radial loads, making them suitable for challenging drilling conditions and deep well projects.
PDC Cutter Enhanced Three Cone Drill Bit
We provide PDC cutter enhanced three-cone drill bits, which combine the crushing action of cones with the shearing action of strategically placed Polycrystalline Diamond Compact (PDC) cutters on the bit’s gauge or cone. This hybrid design significantly improves performance in transitional or interbedded formations.
Roller Reamer Three Cone Drill Bit
We offer roller reamer three-cone drill bits, which integrate reaming elements on the bit’s gauge pads. These bits not only drill the hole but also simultaneously ream it to ensure the drilled hole maintains a consistent and correct diameter, which is crucial for casing installation and hole stability.
tricone roller drill bits
We offer an extensive selection of tricone roller drill bits, engineered for peak performance across all drilling applications. Our range includes bits with various cutting structures, from durable tungsten carbide inserts for hard rock to aggressive milled teeth for softer formations. Designed for superior penetration rates and extended tool life, our tricone bits provide reliable and efficient drilling solutions for your projects worldwide.
Customize Your Desired Three Cone Drill Bit
Cutting Structure Configuration
We precisely configure the cutting structure based on the specific rock formation you’re drilling. Whether it requires aggressive milled steel teeth for softer, non-abrasive rock or high-grade tungsten carbide inserts (TCI) in various shapes for hard, abrasive formations, we optimize the design for maximum ROP (Rate of Penetration) and durability.
Bearing System Optimization
We carefully select and optimize the bearing system to meet your operational demands for bit life and performance. Options include robust sealed bearings for extended runs in challenging environments, or more economical open bearings for shallower drilling. Our goal is to provide a bearing system that ensures reliable and long-lasting performance.
Gauge Protection Enhancement
We integrate advanced gauge protection features to maintain consistent hole diameter and extend bit life in abrasive conditions. This involves adding wear-resistant materials like carbide inserts on the shirttail and gauge pads. These enhancements minimize wear on the bit’s diameter, preventing under-gauge holes and maximizing drilling efficiency.
Shirttail and Cone Shell Reinforcement
We can reinforce the shirttail and cone shell areas for increased durability in highly abrasive or challenging formations. This involves applying hard-facing materials or incorporating wear-resistant inserts to critical areas, protecting the bit body from erosion and impact damage, and extending the bit’s overall service life in harsh drilling conditions.
what is a three cone drill bit?
A three-cone drill bit, also commonly known as a tricone bit, is a type of rotary drill bit featuring three independent, rotating cones mounted on a steel body.
Each cone is equipped with cutting elements—either milled steel teeth or tungsten carbide inserts—that fracture and shear rock as the bit rotates on the bottom of the borehole. This design allows for continuous engagement with the rock, efficiently breaking it into small fragments that are then flushed away by drilling fluid, making it highly effective for a wide range of geological formations.
three cone drill bit design
A three-cone drill bit is intricately designed for efficient rock excavation, featuring three independently rotating cones.
Cones (No. 1, No. 2, No. 3): These are the primary rotating elements, each strategically positioned to cover the entire bottom of the borehole.
Tooth Crest & Tooth Root: The sharpest point of the cutting element and the base where it connects to the cone, respectively.
Interrupted Tooth: A tooth designed with a break to enhance self-sharpening or improve rock fracturing.
Cutter Groove (Intermesh Area): The space between adjacent teeth on different cones that allows them to intermesh, improving cleaning and cutting action.
Tooth Deletion: Intentional removal of teeth in specific areas, often to create space for larger teeth or optimize chip removal.
Reaming Groove & Spearpoint: Features on the cone or cutting structure that help maintain hole gauge and provide initial penetration.
Gauge (with L/T Configuration): The outer diameter of the bit, designed with specific configurations (e.g., L or T) to maintain the borehole’s correct size, often with hardfacing for wear resistance.
Trailing Flank (Full Hardfacing) & Leading Flank (Partial Hardfacing): Different parts of the tooth’s side, with varying degrees of hardfacing applied to enhance wear resistance and direct cutting forces.
where to use three cone drill bits?
Three-cone drill bits are highly versatile and widely deployed across numerous drilling applications due to their effectiveness in various rock formations.
Oil and Gas Exploration & Production: They are extensively used for drilling deep wells, from soft surface formations to hard, abrasive reservoir rocks, in both onshore and offshore environments.
Mining Operations: Essential for blast hole drilling in surface and underground mines, aiding in the fragmentation of rock for excavation of minerals and ore bodies.
Water Well Drilling: Employed to create boreholes for accessing groundwater for agricultural, municipal, and industrial water supply.
Geothermal Energy Projects: Used to drill into high-temperature, hard rock formations to harness geothermal energy for power generation.
Civil Engineering & Construction: Applied in foundation drilling for large structures, tunnel boring, and other infrastructure projects requiring rock excavation.
