Product Description
Carbide button is a type of rock drill bit widely used in geology and mining tools. The cemented carbide material has high hardness, good wear resistance and heat resistance, and the hard alloy drill bit has strong impact resistance, and has small loss and long service life in rock drilling and excavation processes.
When selecting a cemented carbide bit, it is necessary to selects the impact resistance and wear resistance of the cemented carbide material according to its special working environment. The parameters such as flexural strength, density, hardness, porosity and average particle size of tungsten carbide can reflect the impact resistance and wear resistance of the cemented carbide bit. In addition, these properties depend not only on the physical and mechanical properties of the cemented carbide material itself, but also on the robustness of the overall bit housing, the frequency of the impact power meter of the equipment, and the rationality of the technology used.
