Rotary drilling up to 10 5/8” (270 mm) – Multi-pass

The Atlas Copco IDM 70 is a crawler mounted, hydraulic tophead drive, multi-pass rotary drilling rig specifically designed for production of blasthole drilling to depths of 124 ft (38 m) with a 25 ft (7.62 m) pipe change and 140 ft (42.6 m) with the optional 35 ft (10.7 m) pipe change.

Various carousel capacities are available for both the standard 25 ft (7.62 m) and the optional 35 ft (10.67 m) tower. Feed pressure generates a weight on bit force of up to 80,000 lbf (360 kN). It is available in diesel and electric version.

FOPS certified operator’s cab

allows to perfom tower pinning and pipe changing remotely

Excellent visibility with an unobstructed view

of the drill table for the operator

The powerpack maximizes mechanical efficiency

and isolates the components from drilling and propelling shock loads

  • The “on-off” regulation system of the compressor can remove load during non-drilling operations. This extends compressor life, saves energy and provides easier startup
  • Air condition is also provided as an option.
  • The engine and airend combinations are designed to deliver optimum air and horsepower to meet the toughest drilling conditions without sacrificing power
  • There is also an optional angle drilling package that allows the tower to be positioned up to 20 degrees from the vertical position.
