COP66 convex 171mm cemented carbide steel DTH Drill Bits
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 alloy steel is very strong and has long service life.
Strong torque, head design rich for different geological needs.
Standard of work size. Reduce wear and tear to screws and extend service life.
Different sizes and sizes. Meet the needs of different airlines.
