Miracle 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 DH bit and drill pipe.
Highlights
The simple structure design reduces downtime to a large degree;
It is short, lightweight and safe;
Miracle’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.
