Our percussion rotary drill rods range meet your needs for your geotechnical and construction drilling. We produce our drill rods thanks to the welding friction in France to gain in resistance and quality on your sites. Our manufacturing plant situated in Carros, France has the ISO 9001-V2015 certification.

Here are the advantages of the welding friction:
• Seamless steel tubes.
• High-strength heat treated steel tool joints.
• API threads.
• Tool joints friction welded onto the mid body.
