Terracore conventional steel drill rods are all manufactured with friction-welded couplings. The couplings are hardened, which offers increased wear resistance and greater strength in threaded connections. The mid body is thin-wall to reduce weight for increased depth capacity. Terracore steel rods are lighter than standard steel without compromising wear resistance or quality. Threads are surface-treated for easy jointing and extended life.
Features & benefits
- All rods are manufactured with friction-welded, hardened and surface-treated couplings.
- Thin-wall, high-quality steel in the mid body reduces rod weight and increases depth capacity.
- High-quality steel and hardened couplings provide long service life.
- Strict straightness tolerances ensure low vibrations at high rotation for improved core sample quality.
