SANDVIK RETRAC BIT 115 MM GT60 RT300

Five Reasons Why The GT60 Drill 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. 

Compared to the T51 drill rods, GT60 rods have a 40% larger rod cross-section and a 65% higher bending resistance. These improvements double the life of the drill rods and shank adapter. As an added bonus, the rigidity of the GT60 drill rods permit optimum drilling patterns and higher rates of penetration
