Our drill rods are made of 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 rods have drilled up to 2000 meters depth. Geotec has many years’ experience in manufacturing coring drill rod, we try to provide you the most cost-efficient products.Features of Drill Rod

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.
