Down-the-hole drilling (DTH) essentially involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation and air.

Dec 4, 2024 · Engineers should consider using low-pressure DTH hammers in their drilling operations to improve drilling performance and reduce maintenance costs. Furthermore, low …

A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small …

We offer a complete range of dth drilling tools including hammers, bits, pipes, adapters, reverse circulation products, breakout benches and grinding machines with consumables.

Optimal energy transfer is essential to DTH drilling efficiency – how much compressed air power is transferred from the piston to the bit. That is why we have revolutionized air flow …

Drill King’s DTH Air Hammers are engineered to deliver high-impact energy, making them ideal for quarrying applications. The high-frequency design ensures rapid penetration, enhancing …

Feb 4, 2025 · DTH drill bits are specialized tools designed to break through rock and other geology during drilling operations. They are attached to down-the-hole (DTH) hammers and …

The DTH hammer is pneumatically driven, with compressed air propelling it forward to impact and break the rock. The reciprocating motion of the piston is controlled by the gas distribution …

Feb 25, 2025 · DTH (Down-the-Hole) hammer drills use compressed air to deliver powerful blows to the drill bit, allowing efficient drilling through hard rock formations with precision and speed.
