Product Description

DTH hammers and bits are widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering.

it has the advantage of high flatness, smooth hole wall, high rigid of drill rod and hammer, independent of high axial thrust, no limit of drilling depth, low cost of devices and easiness to maintain.



 

ADVANTAGE:
* Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to the special  inner structure of DTH hammer designed according to newest rock drilling theory.

* Smooth performance and long service life of DTH hammer due to high quality alloy steel materials and advanced processing technology adapted.

* Low problem rate and easy to maintenance due to simple, reliable and easy assemble and disassemble inner structure of hammer.

* Easy to depart bit from hammer due to multihead thread connecting chuck and cylinder of hammer.
Interchangeable with DTH bit and drill pipe. Low pressure and high pressure hammers are available in our company
