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.

Applications

• Underground mining
• Down the hole rock drilling

Competitive Advantage

• High-grade tungsten carbide inserts
• Bit bodies manufactured from high-grade steel and processed using state-of-the-art CNC machinery and heat treatment
