Eccentric PDC Bit Features
- Eccentric Design: The bit has a strategically offset reaming section, which allows it to pass through a smaller casing or wellbore restriction without getting stuck while entering or exiting the hole.
- PDC Cutters: Equipped with PDC (polycrystalline diamond compact) cutters, the bit efficiently shears through rock formations. These cutters are exceptionally hard, wear-resistant, and ideal for high-speed drilling.
- Pilot and Reaming Sections: The bit’s design incorporates a smaller pilot section to drill the initial hole, followed by a larger reaming section that enlarges the wellbore to its final, specified diameter in a single pass.
- Optimized Hydraulics: The bit’s internal fluid channels are designed for optimized fluid flow, which effectively cools the cutters, prevents “bit balling” by clearing cuttings, and improves overall drilling efficiency.
Eccentric PDC Bit Applications
Underreaming and Hole Enlargement: They are used to enlarge a pre-drilled pilot hole, which is essential for passing larger casing or other downhole equipment into the wellbore.
Oil and Gas Drilling: These bits are ideal for complex well designs, like horizontal wells, ensuring a consistent, full-gauge hole for successful casing installation and completions.
Geothermal Drilling: They are essential in geothermal applications for enlarging wellbores in hard, abrasive, and high-temperature formations, ensuring durable and efficient production.
Mining and Water Well Drilling: Used to create shafts and water wells large enough to accommodate the well screen, pump, and other essential downhole equipment.
Directional Drilling: When used with directional assemblies, eccentric PDC bits help to maintain a stable well path while simultaneously enlarging the hole for improved control and efficiency.

Customize Your Desired Eccentric PDC Bit
Body Material and Design
We offer both steel-body and matrix-body designs. Our steel-body bits are easily repairable and feature a larger blade-to-junk slot area, while our matrix-body bits provide superior erosion resistance, ideal for abrasive formations. We optimize the design for your specific drilling needs.
Cutter Selection and Layout
We select the optimal PDC cutter size and shape based on your target formation. Our layout design is customized for each application, arranging cutters to ensure maximum rock removal, enhance durability, and achieve the highest possible rate of penetration.
Gauge Protection
We integrate different gauge protection methods to extend the bit’s life and ensure the drilled hole remains at the correct diameter. This includes strategically placing diamond-enhanced inserts, wear pads, and durable cutters on the gauge to resist wear.
Hydraulic Optimization
We custom-engineer the nozzle and junk slot placement to ensure efficient hydraulic performance. This allows for superior cooling of the cutters, rapid removal of cuttings, and prevention of bit “balling,” all of which improve drilling efficiency.
what is eccentric casing System?
An eccentric casing system, also known as an ODEX (Overburden Drilling with Eccentric Casing) system, is a specialized drilling method designed to simultaneously drill and install a casing tube in loose, unstable, or difficult-to-support formations.
It works by using a down-the-hole (DTH) hammer and a unique eccentric bit with a reaming wing that swings out during rotation. As the bit drills, it creates a hole slightly larger than the casing, allowing the casing to follow immediately behind.
This process prevents the borehole from collapsing, which is a common problem in overburden layers like gravel, sand, or fractured rock, ensuring a stable wellbore for future operations.
why choose Eccentric PDC bit?
You’d choose an eccentric PDC bit for projects requiring simultaneous drilling and hole enlargement. Its unique design allows it to underream the hole as it drills, which is crucial in unstable or overburden formations where the borehole might otherwise collapse. This all-in-one process significantly reduces non-productive time, as you eliminate the need for a separate reaming trip.
Increased Efficiency: Combines two operations into one, saving significant time and reducing overall project costs.
Hole Stability: The simultaneous drilling and casing installation prevent borehole collapse in challenging, loose formations.
Versatility: It can pass through pre-installed casing while tripping in or out of the hole.
High Performance: Uses high-durability PDC cutters to achieve a high rate of penetration in a variety of formations.
