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. Low cost.
