Ditch Witch releases new AT40 directional drill

Check out the new AT40 HDD released by Ditch Witch that features, what they say, is an advanced two-pipe All terrain drilling system

Ditch Witch has released the new AT40 All Terrain horizontal directional drill (HDD).

The machine features what they say is an advanced, two-pipe All Terrain drilling system that provides 33% more torque than competitive units.


The newly optimised All Terrain drilling system includes multiple patent-pending designs that improve downhole operation.

An inner-rod design provides a flush system that improves tool-joint durability and steering in hard rock conditions. To further improve steering and optimise fluid flow, a reliable All Terrain connection reduces the risk of collar damage.

The All-Terrain system also features an enhanced reliable RockMaster® housing for improved longevity and reduced maintenance. The modular design makes the housing adaptable to two different sizes of drill bit, allowing a 2.875 and 3.5 regular api connection.

A patented floating-spindle design makes it easier and more cost-effective to replace. The new housing also features an industry-exclusive, double-layer seal with high-capacity bearings for increased downhole life, doubling service times compared to previous models.

Further enhancing productivity, the new All Terrain drill leverages the same next-generation features of the standard JT40 model. A 160hp (gross), Tier 4 Cummins® diesel engine offers up to 40,000 (2758bar) pounds of thrust and pullback.

Improved drilling efficiency is provided by a two-speed, rotational drive system that produces 7457Nm of torque. The drill is also equipped with a 264-litre, 75.84bar mud pump to increase fluid flow from the pump to the swivel.
