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;
3. New Diamond's bits are widely used in different rock formations like carbonate rock,limestone,chalk rock, clay rock,siltstone and sandstone;
4. It can greatly reduce the drilling cost, because of its high drilling speed and life span, which reduces the times to changes bits in the drilling service.

The appearance of the picture is different from that of the actual product, and the actual product is the standard.
