HIP Tungsten Carbide Mining Drilling Tips for Rock / Oil / Coal Drilling Bits
Tungsten Carbide Drilling Tips for mining are mainly known as tungsten carbide buttons, For rock drilling and percussion tool, drilling in soft ,medium and hard formations.
By using carbide drilling tips, with its superior wear resistance and impact toughness, The speed of drilling and digging will be more faster than other same kinds product.
Our 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 etc.
Introduction of Carbide Mining Drilling Tips:
1. Grade: YG8, YG11, YG11C etc.
2. CIP pressed,extruded ,HIP sintered
3. Application for mining and oil-field rock tools.
4. Tungsten carbide tipped center
5. Hard Metal / Performance: It is fitting for serving as drill heads of heavy rock-digging machinery, plumbun heads are used in deep hole drilling and rock drilling terrace vehicles.
Advantages of Drilling Tips for Rock / Oil / Coal Drilling Bits
100% Virgin Raw Materials
Different surface treatment reaches surface accuracy.
Good welding performance
Strict quality control
