CD- 75

CoreDrill- CD75 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 drills are built with long experience and knowledge which


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 - 950 Meters (3116ft
  • N-Size - 750 Meters (2460ft)
  • H-Size - 455 Meters (1492ft)
  • P-Size - 300 Meters (984ft)

Note: Diamond core drilling Depth are based on Straight, Vertical, Clean fluids fill holes.

The depth capacities mentioned above are calculated by field experience. Actual drilling capacity depends on conditions, drilling techniques, In-the whole tools and equipment used.
