Down the hole rock drill bits dhd340 dhd350 dhd360 dhd380
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
The New Diamond manufactured dhd380 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.

| WE can design and manufacture according to customers requirement of
the bit diameter,the NO.of air holes,carbide buttons and the face
shape. |
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.
