two cone drill bit design

Pin: This threaded connection at the top of the bit allows it to be securely attached to the drill string.
Leg: The main body of the bit that extends downwards from the pin, supporting the cones and housing internal components.
Cone: The two conical structures at the bottom of the bit that rotate independently and contain the cutting elements.
Tungsten Carbide Insert Cutter: These are the hard, wear-resistant inserts embedded into the surface of the cones, responsible for breaking and crushing the rock.
Nozzle: Ports on the bit face where drilling fluid is expelled at high velocity to clean the cutters and remove cuttings from the borehole.
Lubricant Reservoir: An internal chamber that holds lubricant to ensure smooth operation and extend the life of the bit’s bearings.
Seal: A critical component that prevents drilling fluids and abrasive particles from entering the bearing assembly, protecting the lubricant and bearings.
Bearings (Ball Bearings, Journal Bearing): These allow the cones to rotate freely on their respective axles. Ball bearings handle axial and radial loads, while journal bearings (often friction bearings) provide robust support for heavy loads.
Ball Hole: A channel that facilitates the insertion of ball bearings during assembly and retains them in place.

Dual Rotating Cones: The core design features two independent, rotating cones at the bottom of the bit. These cones are strategically angled to ensure full coverage of the borehole bottom as the bit rotates, maximizing rock fragmentation.
Cutting Structure Variation: The two cone rotary drill bits can be equipped with different cutting elements. One image shows milled steel teeth, ideal for softer formations due to their aggressive scraping action. The other image depicts tungsten carbide inserts (TCI), which are more durable and suited for harder, more abrasive rock by crushing and chipping.
Threaded Connection: At the top of each bit, there’s a threaded pin connection. This allows for secure and strong attachment to the drill string, ensuring efficient transfer of rotational power and weight from the rig to the bit face.
Hydraulic Nozzles (implied): While not explicitly detailed in all views, rotary drill bits typically incorporate nozzles on the bit face. These nozzles direct high-pressure drilling fluid to clean the cutting elements, cool the bit, and efficiently flush rock cuttings from the borehole.

Customize Your Desired Two Cone Drill Bit

Cutting Structure Optimization

We meticulously customize the cutting structure based on your specific rock formation’s hardness and abrasiveness. For softer rock, we can design aggressive milled teeth. For harder, more abrasive formations, we offer various tungsten carbide insert (TCI) geometries and grades, ensuring optimal penetration rates and extended bit life for your project.

Bearing System Selection

We tailor the bearing system to match your drilling requirements for bit longevity and performance. For extended runs in challenging conditions, we recommend robust sealed or journal bearings. For applications where cost-effectiveness and shorter runs are primary, we can provide open bearing configurations, ensuring the right balance for your operational needs.

Connection and Size Compatibility

We guarantee seamless integration with your existing drilling rig by customizing the bit’s connection type and size. This involves precisely matching the API threaded connection to your drill string specifications. A perfect fit prevents operational issues, ensuring secure attachment, efficient torque transfer, and reliable performance during drilling.

Hydraulic and Nozzle Configuration

We fine-tune the hydraulic design by customizing the number, size, and placement of the nozzles. This optimization ensures efficient cleaning of the bit face, effective cooling of the cutters, and superior removal of rock cuttings from the borehole. Proper hydraulics are crucial for maximizing penetration rates and overall drilling efficiency.
