High Air Pressure DTH Hammer with Foot Valve

Introduction to DTH Drilling Hammer

DTH Drilling Hammers are most used in hard rock formations and are designed to tackle complex tasks like drilling in populated areas without putting existing structures at risk. In these areas, they are ideal for drilling large diameter boreholes in hard rock formations, typically ranging from 3 inches (85mm) to 48 inches (1219mm) or more.
Another advantage is that DTH Drilling Hammers can achieve greater depths drilling in hard rock than other methods. Depending on the size of the hammer and the rock formation being drilled, DTH hammers can achieve depths of up to 1,000 feet (305 meters) or more.
DTH Drilling Hammers therefore offer drilling efficiencies with a high rate of penetration (ROP). This is down to the fact that the air-powered hammer consistently minimizes energy loss to the drill bit, allowing it to break down the rock efficiently. Additionally, the compressed air flushes out the cuttings, reducing the likelihood of clogging or binding the drill bit.
High pressure air is often necessary for efficient flushing of the bit – but caution is required when working with overburden ground where unconsolidation can compromise existing foundation stability.
