Triple-ridged diamond elements
Better absorb impact loading to reduce the effects of impact damage.
Torque-reducing ridged diamond element cutter block
In medium to hard formations with unconfined compressive strengths (UCS) greater than 5,000 psi [35 MPa], conventional cutter blocks lack the necessary stabilization qualities to reduce torque while improving performance during hole-enlargement-while-drilling (HEWD) operations.
The AxeBlock torque-reducing ridged diamond element cutter block improves rock cutting efficiency through a combination of shearing and crushing actions. A unique geometry gives the Axe ridged diamond element a 70% thicker diamond table than that of a conventional cutter, providing increased frontal impact resistance. For operators, this means that the AxeBlock cutter block delivers improved durability and dull condition for maximum ROP throughout HEWD run.
The AxeBlock cutter block also features diamond semiround top inserts behind the Axe elements to improve block stability by restricting lateral movement and axial impact. The reduced cutting force required and improved stability translate to less overall torque, minimizing reactive torque fluctuation, and providing better toolface control. This enables better build rates and higher overall ROP, helping maximize production zone exposure and minimize drilling time.
