Rockmore’s Vector Rod breakthrough
Rockmore International officially unveiled its new
Vector Rod System to the North American market
at MINExpo 2016. Conceived to be a major
breakthrough in improving performance and
service life of extension drill tools in surface and
underground percussive drilling applications, the
new line of drill tools “promises tremendous
advantages in productivity and reliability”, says
the company.
“After several years of intense research and
development followed up with monitored field
tests in various ground conditions, Rockmore
engineers developed a new thread design, XT, for
the Vector Rod System. The new XT design
incorporates revolutionary new guided cylindrical
contact zones between the male and female
thread joints. These guided surface features are
located in the nose and rear of the thread
connections and serve various benefits and
improvements over traditional threads.”
The XT thread profile is based on the
traditional trapezoidal “T” thread design and is
therefore compatible with industry standard
thread types such as T38, T45, and T51. “Thus,
one can interchange and connect standard “T”
style threaded components with the new XT
thread, although the guiding advantages
aforementioned would be neglected. For
example, a T45 threaded bit or shank adapter can
be connected to a XT45 threaded rod with full
compatibility. In order to achieve the full
engineered benefits of the XT thread, however,
one must consider the drill string as a system of
connections between the shank adapter, rods,
and the bit in extension drilling applications.
Thus, the XT thread design employed in the
Vector Rod System enables many performance
and reliability benefits leading to major overall
cost savings in the drilling cycle.”
“We specifically targeted an increase in thread
service life while enhancing drilling performance
in extension drilling applications,” says Pejman
Eghdami, Executive Vice President of Rockmore
International, in explaining the goal of
developing the Vector Rod System. The dual
cylindrical contact zones in the nose and rear of
the XT threads significantly increase the lateral
support between thread joints and stabilise the
connections with more rigidity to provide better
energy transfer. The enhanced thread support
and geometry extends thread life and increases
the overall component service life of the shank
adapters, rods, and bits with XT threads that
comprise the Vector Rod System.
“Because the XT thread guide feature improves
thread alignment, the impact duration when
‘rattling’ rods, as required in uncoupling
connections, is minimised. This leads to lower
wasted energy transmission, cooler couplings on
rods, and ultimately to longer rod life. Thread
