1.10 years manufacturing experience;
2. Certificate: ISO9001:2008
3. Material: Carbide
DTH Drill Bits are one of our main products. After many years development, we have rich experience in develop and manufacture high quality DTH hammer drill button bits, which adopted high-quality raw materials, advanced technology and passed through strictly inspection.
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.
