Product Details

Properties: High pressure DTH hammers as ROS series which drilling speed is the best speed in the world, they need the least airflow in work. Their quality is the best stability. And also are widely used in ground project for diving all kinds of middle hardness, high hardness and somehow worse drillability rocks.



Characteristics are as follows:

1. This kind of hammer is designed as a strong-wind system, which can have all the high-pressure gas flush off with an aim that keep the hole's bottom clean. The durable piston on the hardness treatment can have two end changed, which can extend the working life.

2. Designed a changeable vapour look, which can change the gas charge according to rocks'hardness and abrasion resistance to realize the best flash effect and highest drilling efficiency.

3. Simple structure and few but wearable spare parts make longer working time.

4. Front joint adding with a multiply heads thread makes the disassembly much easier.


Products Scope:

Boosting holes in mine, roads projects, drilling holes in protacting landslides and dams and so on.
