Applications
The New Diamond manufactured dhd350 is widely used in geological
exploration, coal mine, water well drilling, borewell drilling,
highway, railway, bridge, construction, mining, quarry, Civil
engineering, ore mining,Dimension stone industry 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. Stable drilling speed: the bit is scraped and cut to break the
rock.
4. Good performance: strong wear resistance, good diameter protection which will make
the cutting teeth more efficiently.
5.Lower cost.
The appearance of the picture is different from that of the actual
product, and the actual product is the standard.
