GT60 Thread button bits

Five Reasons Why The GT60 Tungsten Carbide Button Thread Bit

1. The GT60 system includes button bits to comply with all kinds of rock formations and drilling site conditions.

2.The GT60 system provides double the penetration rate, consuming half the energy compared with DTH drilling.

3. The Ø 60 mm rod cross-section is optimized for high-energy transfer of impact power in top hammer drilling of Ø 92 to 152 mm holes. Compared with 51 mm rods, the 40% larger cross-section and 65% higher bending stiffness permit faster penetration rates and straighter holes.

4. GT60 is perfectly suitable for automatic rod handling systems. Male and female (MF) threads minimize energy losses and simplify handling.

5. The large flushing holes provides superior removal of cuttings and improves drilling performance. The exact centering of the hole during manufacture ensures uniform steel walls and uniform product performance.
