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.
