Vector rod system improves drill tools’ performance

March 9, 2017  By Administrator

Rockmore International has a new line of drill tools designed to improve the performance and service life of extension drill tools in surface and underground percussive drilling applications

The vector rod system promises greater reliability and productivity, Rockmore said in a press release.

The new XT thread design incorporates guided cylindrical contact zones between male and female thread joints. These guided surface features are located in the nose and rear of the thread connections and provide various benefits and improvements over traditional threads, the company said.


The 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.

In order to achieve the full, engineered benefits of the XT thread, however, users must consider the drill string as a system of connections between the shank adapter, the rods and the bit in extension drilling applications, the company said.

Because the XT thread guide feature improves thread alignment, the impact duration when “rattling” rods, as required in uncoupling connections, is minimized, leading to lower wasted energy transmission, cooler couplings on rods and longer rod life.

The system is available in button bit, MF rod, and shank adapter configurations. The drill string components come in XT38, XT45, XT51 and XT60 thread types.
