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.
Hunan New Diamond offers top quality DTH hammers and bits which have been tested in the hardest rock formation. Our bits use quality hardened steel alloy for the bit body and premium quality tungsten carbide buttons. With superb performance and long life span. Our bits won high reputation among our customers.
