cross bit/rock drill bit

The ZM cross rock drill 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 are mainly used for hard rock, cross bit and button bit are mainly used for fissured rock. 

They are mainly used in digging 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.
