Drill Rod


 


Introduction of drill rod


 


Roschen drill rods are made of high strength alloy steel tube material, with heat treating seamless steel pipe (following S135 or SAE4130 steel) and they are commonly used drilling tools. The pipe of the drill rods features high tensile strength, yield strength and straightness, making sure that all drill rods produced here at our company are available in their best performance under any drilling conditions.


Heat treatment and surface hardening of the drill rods help to better protect the threaded connection and improve its performance in wear resistance and giving the drill rods longer service life.


Our drill rods are suitable to drill deep holes. From drillers’ feedback, our drill rods have drilled up to 2500 meters depth. Roschen has so many years’ experience in manufacturing coring drill rods, we try our best to provide you the most cost-efficient products.


 


Features of Drill Rod:


1. Mad of high quality alloy steel pipe tube


2. All our drill rods are heat-treated.


3. Reasonable structure, reliable performance and high using efficiency.


4. Good concentricity, high precision and long service life.

Notice for products application


Ensure that the screw thread be lubricated by grease lubricant, bringing the drill rods longer service life.

Conducting regular inspection to the screw thread of the drill rods and if any damage of the screw thread appears, it must be changed in time to avoid further damage on other drill rods connected with it.
