Take drilling performance to the next level in any application
Since its introduction in 2012, the Baker Hughes Talon? family of bits has been proven as the industry standard for PDC bits, delivering high-performance cutting, mechanical, and hydraulic efficiency. Both the Talon and Talon 3D products still deliver superior directional control and high build-up (BUR) and penetration rates (ROP) in challenging environments.
The newest advancement in bit technology—the Talon Force PDC bit—builds upon this foundation by introducing improvements to cutting and mechanical efficiency through:
- Next-generation cutter technology;
- Cutter geometry enhancements ;
- Optimized cutter layouts ;
- Lateral stability improvements.
Talon™ Force high-velocity PDC drill bits combine industry leading cutter technology with customized cutting structures that push performance to the next level. Talon Force bits stay sharp longer, maximize mechanical and cleaning efficiencies, and ultimately provide improved ROP, longer run life, superior directional control, and enhanced durability.
King Cutter PDC cutting technology
Baker Hughes King Cutter™ PDC cutting technology improves the rate of penetration (ROP) with a large 1-in. (25 mm) cutter—the largest in the industry—and greater strength. The larger cutter removes more rock than traditional cutters for increased drilling efficiency in vertical and directional applications.
As an extension of StaySharp 2.0 premium polished cutter technology, King Cutter technology has been augmented with the latest highpressure/ high-temperature (HP/HT) technologies for superior wear resistance, toughness, and thermal stability.

King Cutter technology provides cutters that are 53% stronger than 3/4-in. (19 mm) StaySharp technology. This improvement leads to added durability for longer runs and the ability to withstand forces associated with drilling at higher depths of cut.
King Cutter technology is also available with Stabilis? reinforced cutter technology for an even greater performance and strength boost.
In the field, King Cutter technology with Talon Force drill bits has set multiple records in applications throughout the world. Initial deployments have improved ROP by 28% or more and have set numerous records.
MaxCut milled bit body reliefs
Baker Hughes MaxCut? milled bit body reliefs increase drilling speed and reduce inherent inefficiencies, enabling operators to complete challenging intervals in less time. Combined with StayTough? hardfacing and the Talon? Force high-velocity PDC drill bit, MaxCut reliefs deliver step change gains in drilling performance.
Boost ROP
Designed to maximize cutter exposure for increased drilling efficiency, MaxCut reliefs significantly improve the rate of penetration (ROP) by removing body material that would ordinarily come into contact with the borehole and induce unnecessary rubbing at high depths of cut. As shown by the images in Fig. 1, the bit with the milled reliefs on the left has less blade contact compared to the standard steel body PDC bit on the right.
Maximize run life
Steel body bits with MaxCut reliefs are equipped with StayTough hardfacing, which combines advanced metallurgy with exacting welding procedures to provide maximum durability. The proprietary hardfacing reduces bit erosion and prevents damage to the bit body from rock formations and debris. It is three times more wear resistant than the traditional tungsten carbide matrix to eliminate any degradation in bit durability.
Saved 230 hours of drilling time
An operator in the Eagle Ford Shale was able to drill the curve/lateral section in record ROP using an 8?-in Talon Force bit with MaxCut reliefs—setting a new benchmark for drilling the curve and outpacing offsets by 35% across multiple counties.
In 20+ runs, the Talon Force bit with MaxCut reliefs saved the operator more than 230 hours of drilling time and successfully completed the curve in 6.5 hours—setting a new ROP record compared to competitive offsets.
StaySharp 2.0 premium polished cutter technology
StaySharp 2.0 premium polished cutter technology maintains a sharp, efficient edge longer for increased ROP and footage. Augmented with the latest high-pressure/high-temperature technologies, StaySharp technology delivers superior wear resistance, toughness, and thermal stability.
Stay sharper longer
For greater durability, StaySharp cutters may incorporate an exclusive Baker Hughes diamond-layering process that combines an abrasion-resistant, fine-grained surface with one or more additional diamond layers. Field proven for more than a decade, the diamond-layering process has been refined through an improved manufacturing process that allows much tighter tolerances.
To further improve the carbide substrate in extreme applications, patent-pending materials can be applied to help prevent erosion and corrosion. The result of a major research effort, these substrate materials were developed in conjunction with a large carbide company and a research university.
Improved cutting efficiency
An exclusive, diamond-polishing process decreases friction on the cutter face to improve wear resistance and run life. With less friction, the cutter remains cooler, which improves abrasion resistance. Polishing also reduces cutter balling, produces smaller cuttings, maximizes cuttings evacuation, and improves ROP.
Superior manufacturing process
All StaySharp cutters undergo a procedure that maximizes thermal stability and wear resistance by removing catalyst metals used in the PDC manufacturing process. This new procedure combines industry-standard chemical processes with a proprietary manufacturing practice that boosts wear resistance by a factor of four or more.
Stabilis reinforced cutter technology
The new Stabilis? reinforced cutter technology from Baker Hughes amplifies cutter durability and delivers longer runs in challenging formations. Where traditional PDC cutters fail, the Stabilis cutter’s novel geometrical design protects the cutters while improving performance.
Stabilis cutters introduce a secondary chamfer on the diamond face of the cutter that enables a higher loading to be applied without breakage. Compared to traditional cutter geometry, Stabilis cutters have nearly triple the impact strength.
The ability to withstand a wear flat is also improved with Stabilis cutters. The additional bevel on the diamond face of the cutter enables compression to spread across more area, leading to a lower stress gradient across the cutting edge. The wear flat tends to stay within the area of the first chamfer, with the second chamfer providing extended protection against chipping and spalling. This extends the life of the diamond face, the cutter, and the bit, so that efficient drilling can continue for longer periods.
Stabilis cutters also generate less torque fluctuations compared to the standard geometry. For changing cut depths, Stabilis cutters have a consistent coefficient of friction, whereas standard cutters have a fluctuating torque response. Controlling these oscillations leads to smoother, more stable drilling resulting in higher rates of penetration (ROP) and improved overall run performance.
With its ability to maintain an efficient cutting edge and mitigate chipping and spalling, the Stabilis reinforced cutter can effectively cut through hard formations at the same or higher speed as traditional cutters for longer periods, while creating less torque and finer cuttings for a cleaner borehole.
Optimized cutter and blade layouts
Taking advantage of the improvement in cutter technology, Talon Force PDC bits use application-specific designs to maximize overall ROP and durability. Bit profiles have been designed to promote ideal cutter loading to meet any drilling objective while maximizing lateral stability, leading to better use of downhole power and more efficient drilling.

Location: Kazakhstan
Challenged by an application that consisted of anhydrite and hard interbedded carbonate formations with extended chert inclusions, an operator in Kazakhstan sought a bit solution that would not only provide durability, but also maintain higher speeds than that seen with diamond impregnated bits.
The unconfined compressive strength (UCS) of the formation typically ranged from 10,000 to 20,000 pounds per square inch (PSI), but would spike up to 35,000 PSI when chert was encountered. Typically, PDC bit cutters would experience excessive damage when drilling the chert, so Baker Hughes recommended its heavy-set, eight-bladed 8?-in. Talon? high-efficiency PDC bit fortified with Baker Hughes Stabilis? reinforced cutters to tackle the varying formations.
The Talon 8?-in. PDC bit with Stabilis cutter technology, with its stable design, durable profile and efficient cutting structure, provided the strength and speed to outpace competitor impreg bits, hybrid bits, and PDC bits with conical diamond cutters in this difficult chert formation. The Baker Hughes AutoTrak? V automated rotary steerable drilling system (RSS) ensured the bottomhole assembly would stay on trajectory and drill a vertical hole.
The goal for the first run of the section was to drill 1,870 ft (570 m) until chert content reached 10% with a target rate of penetration (ROP) of 26 ft/hr (8 m/hr). The beginning section of 295 ft (90 m) consisted of hard plastic anhydrite. Following that was a 656 ft (200 m) section through interbedded and hard carbonate formations with chert levels of up to 60%. Total distance drilled reached 1,946 ft (593 m), a 4% improvement over the plan. The rate of penetration (ROP) drilled was 32.8 ft/hr (10 m/hr), a 250% increase over previous impregnated drill bit runs, and an increase anywhere from 110% to 200% over competitor PDC type drill bits.
The Talon PDC bit also provided the added benefits of creating larger cuttings than previous impreg bit runs for better lithology identification. The bit also required less weight on bit, reducing torque and mitigating bottomhole assembly damage.
Together, the Talon PDC bit with Stabilis reinforced cutters and the AutoTrak V automated RSS saved the client 5.7 days of rig time that equated to an estimated USD 240,000.
