This kind of drill rod is especially suitable for the geological,
hydrological, coalfield, geothermal and engineering drilling. We
provide seven kinds of geological drill rods in different diameters
for customers around the globe: Φ44.5, Φ54, Φ67, Φ89, Φ42, Φ50, and
Φ60.
It is mainly comprised of rod body and joint. And all of its raw
materials have ISO9001: 2000 certificates. And it is cost-effective
and wear resistant, and its service life is quite long.
