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
An increased junk-slot area, due to greater blade height, promotes efficient cuttings evacuation away from the bit face.
Steel construction allows the bit's body diameter to be minimized, which combats bit balling.
Advanced hydraulics delivers maximum cutting-structure cleaning and junk-slot flow.
Optional premium PDC cutters for improved durability for abrasive formations.
Optional anti-balling metallic coating electrochemically applied to the surface of the bit body which reduces the surface roughness and friction. This greatly helps to prevent cuttings from sticking and reduces the likelihood of bit balling.
