SUPER-MD Roller cone bits
ULTRA-HIGH SPEED MOTOR BIT
In consideration of this high speed drilling condition, our factory specially developed the SUPER-ND ultra-high speed motor Roller cone bit that is designed with roller –journal composite bearing and metal face seal .The Roller cone bit is also equipped with advanced cutting structure and special hydraulic system with double extended nozzles that are suitable for high RPM drilling operations ,this new Super-MD Roller cone 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 Roller cone bits should be run with the range of 250 to 600 RPM in order to get better and economic drilling result.
The size range of SMD series Roller cone bit is from 8 3/4 to 11 5 /8 inch ,and IADC varies from 117 to
617.For example :8 1/2 SMD537x.
