Down the hole hammers are connected with down the hole bits to do
the drilling works. New Diamond uses high quality steel and the
best level tungsten carbide as the raw material,with it's special
heating treatment technique and advanced carbide inserting
technique ,the bits perform well even on the hard rock formations
and save the energy to a maximum limit at the same time.
It is mainly used in geological exploration, coal mine, water
conservancy and hydropower, highway, railway, bridge, construction
and so on.

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
3. New Diamond's bits are widely used in different rock formations
like carbonate rock,limestone,chalk rock, clay rock,siltstone and
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.
