CRUSH THROUGH ROCK.
CRUSH THROUGH THE COMPETITION.

THE ROCK DRILLING DYNASTY CONTINUES.

From the first all-terrain drill in 1995 to the compact and powerful AT32, the forerunners of rock drilling are still revolutionizing the industry over a quarter of a century later. Featuring a patented two-pipe All Terrain drilling system, our drills deliver more power to the bit than any other rock-drilling system in their class for unbeatable productivity.

POWER

Drill beats rock every time with our AT32 and AT40 directional drills. With 40,000 and 32,000 pounds of thrust and pullback respectively, these drills offer more thrust in a more compact unit than competitive models.

PRODUCTIVITY

Optimized for industry-leading performance and productivity when drilling in hard rock conditions, the AT32 and AT40 have next-generation features so you can increase jobsite cycle times, improved durability, and greater control.

OPERATOR’S STATION

The operator’s station on our drills is actually built for HDD operators offers industry-leading visibility for the best view to all critical vision points – including ground entrance, wrenches, shuttle-retract location, and rear connection. Features the choice of a climate-controlled cab with tinted glass or an open operator’s station to meet each customer’s individual needs.

ALL TERRAIN

All Terrain technology enables enhanced rock drilling at a low fluid level, decreasing overall jobsite waste, minimizing cleanup 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.

COMPARE MODELS

Unique jobs demand unique solutions.
And with our lineup of all-terrain directional drills, there’s a machine for every job.
