Product Description

Because of economy and powerful drilling capacity, down the hole hammer become an advanced drilling tool for drilling and mining industries. Down the hole hammers and drill bits are designed together to work in perfect unison, giving high penetration rates, long service life and low costs.
How much compressed air power is delivered to the bit is essential to DTH drilling efficiency. And our DTH equipment's precision engineering and high standards can ensure the drilling efficiency,the hammers and bits feature solutions, which optimize impact-energy transmission into the rock. Combining advanced materials technology with skillful design focusing on performance, simplicity and endurance, our DTH tools give high productivity, great reliability and low operating costs. 

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