Description:
The Cross Bits (Cross Type 7Degree 22Taper)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. The drilling tools are 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.
We are a manufacturer specializes in producing kinds of rock drilling tools includes taper chisel bits, cross bits, button bits, tapered drill rods, integral drill steels, plug hole integral steels, pick rods, thread cross bits, thread button bits, retrac button bits, extension rods, shank adapter, coupling sleeve, etc.
All the products adopt the best alloy and high-intensity steel as material according to the different working conditions.
