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.
Applications
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 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.
