Applications
The New Diamond manufactured SD8 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.
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.
