Rockmore’s Vector Rod System is a major breakthrough in improving the performance and service life of extension drill tools in surface and underground percussive drilling applications. The new XT thread design, developed exclusively for the Vector Rod System, incorporates revolutionary new guided cylindrical contact zones between the male and female thread joints. These guided surface features, located in the nose and rear of the thread connections, enable many performance and reliability benefits leading to major overall cost savings in the drilling cycle.
