In consideration of this high speed drilling condition, Kingdream specially develop the SUPER-MD ultra-high speed motor bit that is designed with roller-journal composite bearing and metal face seal. The bit is also equipped with advanced cutting structure and special hydraulic system with double extend nozzles that are suitable for high RPM drilling operations. This new Super-MD bit features high bearing reliability and long working life under high speed drilling conditions. SMD bits have been used on turbo drills in Russian oilfields achieved more than 30 hours of stable working life and the rotary speed is above 400 RPM. It is recommended that SMD bit should be run within the ranger of 250 to 600 RPM in order to get better and economic drilling result. The size range of SMD series bit is from 8 3/4 to 11 5/8 inch, and IADC varies from 117 to 617. For example: 8 1/2/ SMD537x
