Terracore PG wireline steel drill rod (3)
Terracore wire line rods are flush-jointed and made from high-quality carbon steel for superior yield and maximum strength. A wear-indicator groove located behind the pin thread makes it easy to find the joints and check the condition of the rods. All pin threads are surface-treated for easy jointing and long life.
