DTH Hammers
Maxdrill’s DTH hammers, equipped with DTH drill bits, have strong excavation capability and thus are applied in the fields of site investigation, open-pit mining, quarrying and building construction.
Maxdrill’s DTH hammers deliver outstanding drilling performance while reducing the drilling cost. In underground mining projects, they ensure high-efficient transmission of percussive force into the rock, high drilling accuracy and the optimal drilling outcome.
Advantages
- Delivers maximum energy to the drill bit, enabling a fast drilling speed and low air consumption due to the specialized inner structure of DTH hammers. Each one is designed according to the latest in rock drilling theory.
- The smooth performance and long service life of the DTH hammer is due to the high quality alloy steel materials and advanced processing technology used to manufacture the hammer.
- There is a very low problem rate, and maintenance is easy due to the simple, reliable and easy to assemble/disassemble inner structure of the hammer.
- It is easy to remove the bit from the hammer due to the multihead thread connecting the chuck and cylinder of the hammer.
- The DTH is interchangeable with a DTH bit and drill pipe.
Highlights
- The simple structure design reduces downtime to a large degree;
- It is short, lightweight and safe;
- Maxdrill’s patent designs of DTH drill hammers maximize the transmission efficiency of the percussive force;
- Surface of parts are enhanced to be anti-fatigue and thus DTH hammers have longer service life;
- Contact surface area, pneumatic chambers and the percussive rate have been improved to increase the drilling speed.
