PANDADRILL rod using thread system. Drilling precision can be further improved by using this as the first rod in a normal drill string. Furthermore, since this is a speed rod design it will produce straighter holes and at least 10% higher penetration rate in good rock conditions compared to rod and coupling sleeve combination system.
It is well known that the performance of the material could be played well only after going through heat treatment to release its maximum potential, therefore, the choice of material and heat treatment process are important on an equal basis.
