Atlas Copco DHD350 146mm 165mm DTH Hammer Bits
Atlas Copo DHD350 146mm 165mmDTH Hammer Bits
DTH drilling is a percussion system driving a piston inside hammer body with up and down motion by compressed air and transmitting an intensive percussion energy to the bit to enable the drilling by crushing the rock. Drilling method by DTH hammer exerts high drilling performance especially for drilling hard rock and contributes for shortening work schedule. Hence, this method is widely utilized for foundation work, landslide prevention work, quarrying services, marine civil work, etc.

1.10 years manufacturing experience;
2. Certificate: ISO9001:2008
3. Material: Carbide
Applications
Widely used in mines, quarries, earthworks and other engineering drilling blasting hole, guardrail hole,mountain reinforcement, anchorage and other engineering holes, geothermal exploration hole, Well bore and other fields.
1. Long life span: the wear-resist of tungsten carbides is 10-20 times higher compared with other similar materials, which greatly extends the life of the carbide bits;
2. High drilling efficiency: the high grade hardness of the carbides can always stay sharp, which could increase the drilling speeds too;
3. New Diamond's bits are widely used in different rock formations like carbonate rock,limestone,chalk rock, clay rock,siltstone and sandstone;
4. It can greatly reduce the drilling cost, because of its high drilling speed and life span, which reduces the times to changes bits in the drilling service.
The appearance of the picture is different from that of the actual product, and the actual product is the standard.
