Applications

It is mainly used in geological exploration, coal mine, water conservancy and hydropower, highway, railway, bridge, construction and so on.

Feature Advantage

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;
