Description of cross bit:
The cross bit can be used under any rock drilling condition, it's hardly impacted by the model of drill rig and the rock performance. Generally, chisel bit is mainly useed for hard rock, cross bit and button bit are mainly used for fissural rock.
It is mainly used for diging into mine laneway and blasting holes in all drilling works matched with the taper drill rod. For different rock, we choose the different alloy to extend the working life of the drill bits.
