Drilling Casing 600 mm to 3000 mm Flat/ Ws39 Teeth Drilling Casingcasing Drilling Bit

Reliable anti-collapse performance for complicated strata such as quicksand, silt, boulder and karst, prevent hole shrinkage and deviation.

Made of thick Q355 steel with high rigidity, anti-deformation during rotary cutting, sandblasted surface for repeated turnover use.

Equipped with carbide casing shoe teeth, smoothly cut hard rock and boulders, reduce casing driving resistance and speed up construction.

Tight sealed flange/button joints stop sand and underground water infiltration, less sediment inside borehole for better pile quality.

Mud-free dry drilling design, eco-friendly and cut cost of mud treatment and concrete overfilling. Rigid steel casing ensures excellent verticality, ideal for secant pile, foundation pit and bridge pi

Modular segmented design, easy lifting, assembly and extraction, save labor and construction time.

Wide compatibility with rotary rig, casing rotator and oscillator; customized diameter, wall thickness and accessories available.
