MD

High speed motor bit

Working condition of the bit in directional and horizontal drilling applications is quite different than in vertical well drilling .our factory's new MD series motor bit features high RPM , Better gage protection and stability ,higher reliability, excellent hydraulic effect and longer working life etc.MD bit is suitable for drilling at 90~300 RPM and is the ideal choice for directional ,horizontal and horizontal multilateral well drilling applications.

The size range of MD series bit is from 7 7/8 to 12 1/4 inch ,and IADC varies from 117 to 647. for example:8 1/2MD517X.

MINI-MD

ROLLER CONE BIT FOR SLIM HOLE DRILLING APPLICATIONS

In addition to the features of MD motor bit ,MiniMD slim hole bit is also designed with special bearing &Seal structure and lubrication system.MiniMD bit's cutter material and cutting structure are reasonably matches with rock properties of the formation and this eliminated the specific problems such as low drilling efficiency and cutter breakage and loss ,ect. MiniMD slim hole bit is the ideal choice for drilling slim hole sections in deep and ultra-deep well drilling applications
