WIRELINE drill rods


Roschen Wireline drill rods are manufactured from the best quality heat-treated seamless steel tubes. Ultimate tensile strength, yield strength, high precision and good straightness provide the best performance under different drilling conditions.


Case hardening on rods end protects thread connection and increases its wear resistance and rod life. 

Our wireline rods are also suitable for deep hole drilling.

The standard effective lengths of drill rods are 3.0 & 1.5 meters. 

Other lengths can be manufactured according to customers' special requirement.

Roschen has many years of experience in manufacturing coring drill rods, we try to provide you the most cost-efficient products.
