Concentric Casing System with Wings - Elevating Drilling Efficiency
Our concentric casing system with wings boasts a unique design that enables downward pressure and clockwise rotation at the start of rock chipping. This initiates the rotation of the winged expansion block along the rotational axis, facilitating casing advancement while expanding the hole. This cutting-edge system ensures synchronized drilling and casing operations, making it an ideal choice for geothermal wells, water wells, small-to-medium-sized grouting holes, micro-piling, and more.
