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
