Our 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.
(1) Threaded Connection: R22, R25, R32, R38, T38, T45, T51, and so
on.
(3) Length: 600-6400mm.
