YG11C Tungsten Carbide Button Bits / Tips Used for Rock, Oil Drilling / Digging
All the carbide mining button tips and mining drill bits made by our factory are made from virgin raw materials and HIP sintered for the top good quality and high performance. Durable carbide buttons with excellent fracture resistance dramatically improve the service life with the high penetration rates. The consistent performance mainly attributes to our pure raw materials and strict ISO quality control.
Introduction of carbide buttons / button tips
The grade of carbide buttons / button tips is YG8, YG11, YG11C and so on. They can be used in the mining and oil-field rock tools. Their hard metal 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.
Advantages of tungsten carbide mining tools for rock / oil drilling
The raw material of the tungsten carbide buttons bits / tips are made from the riginal raw material. Different surface treatment reaches surface accuracy. Our factory can provide the different packages that you can choose from. At the meantime, Our factory can provide the good welding performance.
