CD- 120

CoreDrill- CD120 is a versatile heavy duty Hydraulic Diamond core drill in compact frame size for surface mineral exploration Applications where the sites are located at remote places & hard to access.


The making itself propelled to access the difficult sites OR it can be Truck Drills are fitted on crawler tracks powered from rig hydraulics Mounted for greater maneuverability and easy to relocate between sites.

Drills are built with well market proven components which providing more Durability, easy to service, user friendly, improved power factor with Highly efficient hydraulics.

Drilling Depth Capacity

Method of drilling Diamond core (Wire line-Conventional)

  • B-Size - 1540 Meters (5052ft)
  • N-Size - 1200 Meters (3937ft)
  • H-Size - 800 Meters (2624ft)
