Our French production of standard rotation percussion drill rods allows us to offer a wide range adapted to your soil testing and construction drilling. We obtained the ISO9001-V2015 certification and we control each type of tool. We selected the friction welding technology for tool joints. This method favors a better strength of the stem combined with the quality of the raw material used.

How do we do the friction welding?
• Seamless steel tubes.
• High-strength heat treated steel tool joints.
• API threads.
• Tool joints friction welded onto the mid body.
