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

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

Strong aggressiveness allows the bits high ROP

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
