The GT60 high-speed drill rod features an innovative thread structure within its drill string components. Compared to T51 drill rods, the GT60 model offers a 40% increase in cross-sectional area, delivering 65% improvement in bending stiffness and significantly extending resistance to impact waves generated by the piston.
Key Benefits
Doubles service life of both drill rod and shank adapter
Wide hole range compatibility with same rock drilling machine
High drilling speed with minimal loss in impact energy transfer
Exceptional drilling efficiency for mechanized operations

Design Features
The GT60 system enables a broader spectrum of hole diameters while utilizing the same rock drilling machine. Engineered specifically for compatibility with contemporary hydraulic top-hammer drills, the GT60 product lineup corresponds to conventional drill rods. The GT60 thread profile is applied to 60mm solid round bar stock.
Industry Standard Practice : The drive end of drifting drill steel is reinforced to boost structural strength at the rock drill interface, supporting larger-diameter shank adapters. Rock drilling tool steel comes in various standard lengths designed to fit drill feed systems of numerous drifting jumbos.
Male / Female Type Advantages
Stiffer joint connections for enhanced performance
Simplified uncoupling and on-site handling
Superior service life compared to designs using separate couplings
Non-replaceable coupling end provides significant operational advantage
Enables use of drill bits with diameters closer to drill steel
Improved flushing efficiency and higher borehole precision
Applications
The GT60 high-speed drill rod is suitable for both surface and underground drilling operations when used with large hydraulic top hammer drills. It facilitates the mechanization of drilling operations and effectively enhances overall drilling conditions across various mining and construction applications.
