DitchWitch® AT40 – All Terrain Horizontal Directional Drill
The DitchWitch AT40 has been optimised for industry-leading performance and productivity when drilling in hard rock conditions, the AT40 has next-generation features so the CDS team can complete those hard rock jobs more efficiently and with greater precision.
The AT40’s All Terrain technology enables enhanced rock drilling at a low fluid level, decreasing overall jobsite waste, minimising clean-up and reducing environmental impact. The inner pipe works as a mechanical motor, driving the bit during the bore, and the outer pipe thrusts the bit forward while steering the drill shaft. During backreaming the outer pipe transmits full machine torque downhole.
