Hydraulic Earth Auger Drill
CTHB hydraulic auger drills are applied to drill holes in the soil, frozen soil, and ground. Based on these drilling functions, it is widely used for digging holes for fence posts, deck footings, tree planting, solar foundations, and other landscaping projects.
It is mainly composed of the motor unit, connection head, Auger drill bits, and extension rod. Our motor units have a gearbox and rotating motor, the hydraulic auger motor connected to the gearbox significantly increases the torque of the earth auger attachment. This also prevents the motor from damage when against the rock during drilling.
Our hydraulic digger drills can be mounted on excavators, skid steer loaders, and tractors by different connection adaptors. CTHB offers earth augers for machines weighted from 1.5 tons to 80 tons…..
“Precision in Every Turn, Power in Every Dig.”
