Tungsten Carbide Mining Drilling Tips/ Coal Auger Tips for Coal Mine Excavator / Coal Drilling
Tungsten carbide mining drilling tips are mainly known as tungsten carbide buttons. They are usually used in the drilling and percussion tools, which are drilled in soft, medium and hard formations. Thanks to the superior wear resistance and impact toughness of the carbide drilling tips, the speed of drilling and digging will be more faster than other same kinds products. The tungsten carbide milling drilling tips are widely used in open-pit mine for mining, quarry, water and electricity engineering, water well drilling, the support of excavation side column and so on.
The introduction of tungsten carbide mining drilling tips
There are some kinds ot the grade of the carbide drilling tips such as YG8, YG11, YG11C and so on. The drilling tips are pressed, extruded and sintered. The carbide drilling tips are widely used in the mining and oil field rock tools. Thanks to the hard metal performance, they are fitting for serving as drill heads of heavy rock-digging machinery, plumbun heads are used in deep hole drilling and rock drilling terrace vehicles.
The advantages of drilling tips
1. 100% raw materials
2. Different surface treatment and surface accuracy
3. Good welding performance
4. Strict quality control
