DTH (down-the-hole) drilling uses a drilling hammer at the bottom of a drill string to drive a piston and provide impact power, which is then delivered into rocks for drilling and crushing. Mining, quarrying, water well drilling, foundation piling, and other industries use DTH drilling. The DTH hammer generates impact power by compressing air, which is then used to drive drill bits and break rocks.
Our factory can supply you with high pressure and medium to low pressure DTH hammers due to its extensive manufacturing experience. It closely complies with API standards and other business norms in China. Given that it was made with high-quality materials and skilled craftsmanship, it is durable.
In addition, it offers the following benefits:
1. Due to the unique inner structure of the DHD series DTH hammer, which was created in accordance with the most recent rock drilling theory, deliver maximum energy to the drilling bit, fast drilling speed, and low air consumption.
2. The DHD series DTH hammer has a smooth performance and a long service life thanks to the use of high-quality alloy steel materials and adapted advanced processing technology.
3. Low problem rates and simple maintenance thanks to the hammer's inner structure that is easy to assemble and disassemble.
4. The multi-head thread connecting the chuck and the hammer's cylinder makes it simple to remove the bit from the hammer.
5. Compatible with drill pipes and DTH bits
