Inner Auger Strings

Inner auger strings na critical component for advanced double rotary drilling systems wey people use for deep foundation construction and geotechnical engineering projects. Dem deploy these hollow or solid drilling tools inside outer casing of double rotary rig, wey work together with outer casing to extract soil and rock material while advancing borehole to required depths. Dual-rotation mechanism of inner auger strings allow drilling crews achieve precise control over drilling rates and torque distribution, making dem indispensable for complex foundation engineering applications where single-rotation drilling no dey efficient or technically sufficient.
