Application

Medium Hard formation of high resist compression strength, and have hard interlayer. Such as argillite, sandstone, limestone and so on.

Feature

Balanced force design of spiral blades endows the bits with good orientation,little radial vibration as well as ability to increase cutter placement

Lo-Vibe depth of cut control insert. In applications in which bit whirl is a problem, the Lo-Vibe option improves bit stability and reduces potential for damage to the cutting structure by restricting lateral movement and reducing the effects of axial impacts.Optimized ROP and bit life. Long drilling intervals without need for tripping.

The reasonable layout of patented PDC cutters in various structures at different locations endows the bits with strong aggressiveness and anti-abrasiveness

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
