Selecting the right hammer

The optimum range of hole size for DTH drilling is 90 mm (3.5”) to 254 mm (10”). Smaller holes are generally drilled using tophammer drill rigs, and larger holes generally use rotary drill rigs.

Advantage

• Industry leading steerability
• Outstanding rate of penetration
• Simple design allows for field maintenance
• Reduced air requirement results in lower cost per foot
• More efficient and durable internal design
• High frequency operation of rock drills provides less vibration
