Application
 
Soft formation of low resist compression strength, high drill ability. Such as shale, clay, rock salt, cotton rock, and so on.
 
Feature

• Thermally stable polycrystalline (TSP) diamonds are placed on the leading edge of each blade.
• The simulation technology of dynamic flow field are used in hydraulic design to optimize down-hole flow field,beneficial to improve clearance speed and anti-balling simultaneously.
• Reduced bit height improves bit steerability for directional and horizontal applications. It also reduces slide time and footage by achieving builds and turns more quickly.
• Cutter backing raised to minimize excessive depth of cut because of formation heterogeneity.
• Lo-Vibe depth of cut control inserts that can be replaced when needed (wear, breakage, etc.).
• Thermally stable polycrystalline (TSP) diamonds are placed on the leading edge of each blade.
• Lower than standard nozzle count. Reduced nozzle count to best match drilling, formation, and hydraulic system capabilities; reduces the flow rate required to achieve an appropriate hydraulic horsepower per square inch (HSI); avoids the use of numerous, smaller nozzles that can become pl ed.
