Core Drilling Rigs
CDR series rigs for mineral exploration and geotechnical investigation, NQ/HQ wireline coring to 750 m.
9 core drill rig models
A core rig recovers an intact sample instead of cuttings, which is what exploration and geotechnical work needs for accurate logging. KLR's CDR range runs from the CDR 150 at 100-200 m up to the CDR 750 at 750 m, with the TMC 40 built for NQ/HQ wireline work and the CDR-50 through CDR-2000 range specified in feet for export markets that order that way.

Common questions
What is a core drilling rig used for?
It cuts an intact cylinder of rock or soil out of the ground instead of grinding it to chips, so geologists can log the formation directly. KLR's CDR range covers mineral exploration and geotechnical site investigation.
What depths does the CDR range cover?
The CDR 150 reaches 100-200 m, the CDR 500 reaches 200-500 m, and the CDR 750 reaches up to 750 m. The CDR-50/300/1000/2000 range is specified in feet (164 to 6,561 ft) for markets that order to that standard.
Does KLR's core rig support NQ/HQ wireline coring?
Yes, the TMC 40 is built specifically for NQ/HQ wireline work, where the inner tube is retrieved through the rod string without pulling the full string out of the hole.
Does KLR export core drilling rigs?
Yes. KLR equipment is in use in more than 60 countries across Asia, Africa, the Middle East and Latin America.
