The feature of our geological drill rods

  • Case hardening on rods end protects thread connection and increases its wear resistance and rod life.
  • Our wire-line rods are also suitable for deep hole drilling.
  • The standard effective lengths of drill rods are 3 meters. Other lengths can be manufactured according to customer’s special requirement.
  • Chemical heat treatment
    We use the technology that increases the wear resistance of the thread in dozens of times.
    Completely eliminates
  • We have many years of experience in manufacturing coring drill rods. Also, we always have a large number of drill rods in stock. We try to provide you the most cost-efficient products.

Drill Rod and Casing

Sumpaş manufactures its drill rods and casings by using premium quality cold drawn seamless tubes and best tools available in the market for diamond core drilling. These alloy steel tubes are imported as raw material to ensure excellent tensile strength & elongation characteristics and manufactured in the Sumpaş’s high technology CNC machines.

By considering both the customers’ requirements and the latest developments in the technology.

 Sumpas manufacture upseted drill rods. Tubes with larger internal diameter are used and wall thickness of both ends is increased with upsetting for threading purposes. The final product is significantly lighter and as a result depth capacities of drill rigs are increased up to 30%. As a result of heat treatment process, more durable and resistant threads are formed.
