Product introduction:

The down-the-hole impactor is used in conjunction with the down-the-hole drill bit to have high-efficiency and energy-saving tunneling capabilities. The down-the-hole impact drill bit has gradually become the driving equipment used in the drilling and mining industries. There are high wind pressure and low wind pressure. The low wind pressure DTH series are mainly used in quarries, mining, stone excavation, slope treatment, rock anchoring, underground mining, etc. Due to its low efficiency and high energy consumption, it has been gradually replaced by high- and medium-pressure down-the-hole drilling rigs. At present, it is mainly used for small aperture applications.

Product advantages:

1.The overall structural design is concise to minimize the probability of failure

2.Short overall length, light weight and good safety

3.The patented optimized matching design of the drill bit and the impactor maximizes the transmission efficiency of impact energy

4.The surface of the parts is treated with anti-fatigue strengthening treatment, which has a longer working life

5.Optimize impact contact surface, air chamber and impact frequency to achieve faster perforation efficiency
