The chisel bit is made from grade hard alloy and special steel, generally matched with the light-duty rock drill, to drill the rock hole within diameter of 50mm.
It is widely used in metallurgy mine, geological exploration, water conservancy construction, electricity, traffic, tunnel, quarry, national defence stone project etc,. |

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. |

The tapered rod is used for rock drilling, blasting holes and other drilling works in the quarries, coal mines, traffic and other constructions.
Generally, the lightduty rock drill uses 7 taper or smaller taper angle, the heavyduty rock drill mainly uses 12 taper angle.

The integral drill steel has these advantages: it reduces the expense of impact energy, improves the drilling speed and efficiency, there is no limit for the drilling direction and the low-limit of diameter.
All the advantages make this type steels not only apply to the excavate project, but also the outdoor-drilling downwards.

The plug hole integral drill steel is widely used in stone pit field to drill small holes.
Because of the integration of the rods and bits, it can be metched directly with rock drills without shank adapter or coupling sleeve, these advantages avoid the wastage of energy, and improve the drilling efficiency remarkably. |
