Drill pipe and drilling tool features:
1. High-precision CNC lathe processing to ensure the tightness of the thread connection;
2. Special heat treatment process to ensure that the connecting thread has sufficient strength and wear resistance;
3. The body of the drill rod and the joint are welded by a friction welding process, and then the intermediate frequency return is used to remove the welding stress to ensure the welding strength and the straightness of the finished drill rod.
4. The drill rod body and joint are made of European and American high-quality raw materials to ensure the superiority of normal construction under harsh conditions.
