MAXDRILL DTH hammer and DTH Bit

DTH hammer and bits are economy and powerful drilling capacity,it is advanced drilling tool for drilling and mining industries

MAXDRILL Down The Hole Hammer

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.
