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.
