Drill rod using T51 thread system.
With wrench flats to aid in coupling/decoupling of rods for
extension drilling.
Used in benching and long hole drilling.
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
