In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.

DTH drilling enables drillers to reach hole depths that are double of what top hammer drilling can do. This is possible with the use of DTH Pipes and DTH Subs.

• High grade steel used on thread area and main drill pipe body
• Automated welding process used in joining the thread area and main drill pipe body

Applications

• Underground mining
• Quarry benching operations
• Water well drilling

• Blast hole drilling

Competitive Advantage

High strength chromium-molybdenum steel with high fatigue strength and excellent wear resistance
