Machine tool casing MDC76/7RR-01

Concentric Casing System With Ring Bits Application Range Applied to overburden formations with complex topographic and geological conditions, such as gravel, fissured formation, boulder, landfill of construction refuse, etc. Drills at any angle; Good straightness of borehole; Maximum depth of borehole can reach 150 meters. Structural Advantages ♦ Straightness: ensures the straightness of borehole in different topographic and geological conditions. ♦ Adaptability: ensures penetration efficiency in complex topographic and geological conditions, such as gravel and landfill of construction refuse. ♦ Lower torque: the system torque is less than eccentric casing system. ♦ Easy to unlock an re-rock: easy to re-rock after unlock. ♦ Drilling at any angle: concentric casing system can drill under horizontal, vertical and inclined conditions. ♦ Environmental: better than eccentric casing system, because of its advantages of drilling smoothly, small vibration and low noise, it is more suitable for construction in urban areas.
