Hard Rock Drilling Tools Introduction

Down-the-hole (DTH) hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a spline drive for rotating the bit in the ground.

Roschen RH510 is a down-the-hole (DTH) hammer engineered for high penetration rates and maximum productivity. This hammer for high performance is the first choice for drilling hard and abrasive rocks. It features a patented shank design for optimized energy efficiency, and no foot valve. Models with heavy-duty or reversible casings are available to ensure maximal life in high speed drilling applications in abrasive rock formations.

This is achieved through a proprietary interface between the piston and bit. This optimizes impact energy transmission to boost penetration rates. The result will deliver excellent economy through high productivity. It is designed for operating pressures up to 24 bar (350 psi /g) .

Hard Rock Drilling Tools Advantages

1. No pollution, the reverse-circulation DTH hammer can quickly pick up samples on the drill bit surface at the moment of rock fragmentation. The sample does not need to pass through the hammer length, thus avoiding sample contamination and loss.
2. High productivity. In broken and fractured rock, the penetration speed is superior to the ordinary hammer.
3. Dry samples can be collected even in water condition, because drilling cuttings are collected as soon as they produced on the drill bit surface.
4. High sample recovery. Samples are collected from the drill bit surface, so samples loss can be avoided in broken and fractured rock formations. Since the bit diameter is almost equal to the external diameter of the wear sleeve, the sample collection recovery rate can reach 98%.
