Increased cutting efficiency for instant ROP improvement

Field tests of the AxeBlade bit have demonstrated up to 29% improvement in ROP compared with similar bit designs using conventional PDC cutters, resulting in significant rig time and cost savings for operators.

AxeBlade bits employ elements with a unique geometry that cut rock in a new way—a combination of shearing and crushing. This cutting method achieves at least 22% deeper penetration, removing more formation to provide higher instantaneous ROP when using the same WOB and rpm applied to conventional PDC cutters. The diamond table on the element ridge, which is 70% thicker than that of a conventional cutter, gives the Axe element increased frontal impact resistance. For operators, this means that the AxeBlade bit delivers improved durability and dull condition for maximum ROP throughout the run.

Novel-geometry cutters deliver increased impact resistance and instantaneous ROP improvement

Many previous improvements in PDC bit performance were the results of metallurgy and materials changes. That is, until the StingBlade conical diamond element bit was introduced with its unique cone-shaped cutting element. From the success of StingBlade bits, Smith Bits engineers sought to further improve bit performance by developing a new cutter geometry through extensive internal R&D and field testing.

The Axe ridged diamond element features a unique ridge-shaped geometry that combines the shearing action of a conventional PDC cutter with the crushing action of a tungsten carbide insert (TCI). The ridged design of the Axe element enables more efficient cutting and heat dissipation, while also having better frontal impact resistance which is achieved through a thicker diamond layer, proprietary blend of polycrystalline diamond grain-size distribution, and optimized materials.
