Reliable DTH Drilling Tools Dth Hammer Button Bits 3 Inch High Drilling Efficiency
Description
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.
