7 Degree 30mm 40mm For Quarrying Industry Alloy Steel Tapered Cross Bits
Application
The 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.
Cross rock drill bits is mainly available for 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.
Drill bits are cutting tools used to create cylindrical holes, almost always of circular cross-section. Bits are held in a tool called drill, which rotates them and provides torque and axial force to create the hole. Our drill bit is suitable for various ground condition. It is especially efficient and fast when drilling in hard and medium-hard rock.
