Mission60 171mm 203mm Concave Face DTH Hammer Rock Drill Bit
DTH drilling is a percussion system driving a piston inside hammer body with up and down motion by compressed air and transmitting an intensive percussion energy to the bit to enable the drilling by crushing the rock. Drilling method by DTH hammer exerts high drilling performance especially for drilling hard rock and contributes for shortening work schedule. Hence, this method is widely utilized for foundation work, landslide prevention work, quarrying services, marine civil work, etc.

Applications
The New Diamond manufactured Mission60 171mm 203mm 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.
