Forging Dhd340 Dhd350 Dhd360 Dhd380 DTH Hammer Bits
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.

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.
