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.
DTH Drill Bits:
1, Direct sale
2, reasonable price
3. high efficiency
Using:
tungsten carbide button bit drilling series
Suitable for cutting, drilling various hard Non-ferrous materials,
such as marble, granite, glass, ceramic, hard concrete and brick.
Applications
It is mainly used in geological exploration, coal mine, water conservancy and hydropower, highway, railway, bridge, construction and so on.
