Application
PDC drag bit is simply composed of a series of blades (usually three or four in number) which produce a shearing action when rotated. They are comparatively inexpensive due to the lack of moving parts and they can penetrate softer formations such as stiff clays and mudstones very quickly.
Our Advantages
1.Our drag bits strictly meet the API standard.
2.Won a good reputation by the superior quality and services
3.Our drag bits selected high quality PDC cutters, which ensure the bits have high abrasion resistance, fast drilling speed and long life.
4.With advanced equipment, we are committed to quality progress all the time.(extend work life,wear resistance,self-sharpening....)
Parameter
The diameter of this kind of drill bits are from 45mm to 270mm, any special design is available upon customers' request.
