GT60 speed drill rod

Description

GT60 speed drill rod, the drill string components feature an entirely new thread design. Compared with T51 rods, the 40% larger rod cross-section of the GT60 rods provides 65% higher bending stiffness and with stands the Impact-waves from the piston much longer. So much so that both drill-rod and shank adapter life can be doubled. As an extra bonus, the more rigid drill string permits optimum drilling patterns and higher rates of penetration.
Compared with other drilling tool systems, GT60 system permits a wider hole range using the same rock drill. Have been specially developed for use with modern hydraulic top hammers and are available in a similar range to the standard Drill Rods. Plus GT60 Thread on 60mm Round material.
It is common practice to bump up the drive end of drifting drill steel for added strength at the rock drill end to accommodate larger diameter and shank adapters. Drill steel of rock drilling tools is available in many standard lengths to match the drill feeds on a multitude of available drifting jumbos. A rock drill bit diameter closer to the steel diameter can be used since the coupling does not enter the hole, this enhances flushing and hole accuracy.
Male/Female drill steel provides more rigid connections and is easier to uncouple and handle. The service life also tends to be better than with separate couplings. This is fortunate because the coupling end cannot be replaced.

Performance

The applicable scope of GT60 speed drill rods are wide, drilling speed, impact energy transmission loss is small, high drilling efficiency, easily to realize the drilling mechanization and improve the superiority of drilling conditions.

Application

GT60 speed drill rod used for both surface and underground applications on larger hydraulic top hammers.
