Product Details

Drilling hole from 165 to 190mm DHD360 COP64 D65 6 inch Hammers For mining and construction

FEATURES

MIROC offers one of the most complete lines of down the hole drills and downhole bits ranging from 3.5” – 36” (89mm – 914mm) which are designed for peak performance in all rock drilling applications including but not limited to; foundation & geotechnical drilling, blasthole drilling in quarries & mines, waterwell & geothermal boreholes, oil & gas underbalanced drilling, horizontal directional drilling, and utility transmission & distribution rock sockets.

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
