The DTH is the abbreviation of Down The Hole and sometimes it is also called RAB in some markets, then the RAB is short for Rotary Air Blasting.
DTH (down-the-hole) drilling involves a drilling hammer at the bottom of a drill string, the hammer is powered by compressed air transmitted via drilling rod to drive piston and produce impact power, which is then delivered into rocks for drilling and crushing. DTH drilling can be applied in mining, quarrying, water well drilling, foundation piling, etc. DTH hammer uses compressed air to produce impact power, thus to drive drill bits to crush rocks.
• Premium material, fine CNC and heat-treatment manufacturing processes and optimized design;
• Good stability and reliability;
• High impact frequency;
• Lowered compressed air consumption;
• Long lifespan
GSE SD DTH (Down-the-Hole) Hammers have diverse applications across multiple industries. In mining, they efficiently break hard rock formations, enabling faster extraction of valuable minerals. For quarrying, these hammers help fragment large stones into workable sizes, optimizing the stone production process. In water well drilling, they ensure rapid penetration through various soil and rock layers, facilitating the creation of reliable water sources. When it comes to geothermal well drilling, GSE SD DTH Hammers are crucial for reaching the depths required to harness geothermal energy. Additionally, in foundation piling, they assist in driving piles into the ground, providing stable support for construction projects. Their high – performance and durability make them an indispensable tool in these sectors.
