Description:
The hard alloy steel bit used in drilling in hard macadam is not only beneficial to rock breaking, but also has a longer life than the diamond bit.
The drilling speed is low, the centrifugal force is small, and the impact of the drilling tool on the hole wall is small. Moreover, this drilling method uses high frequency impact on the hole bottom to reduce the influence of hole deviation on the broken or inclined formation, thus improving the verticality of the drilling hole and reducing the rock collapse of the hole wall.
