Wedge carbide buttons mainly used for oil & gas tricone bits, oil drilling and mining machine drilling tools. Our wedge carbide inserts has excellent wear resistance and high TRS performance, it’s designed for drilling hard and super hard rock formation. The eccentric wedge carbide buttons also has precise measurement, which ensure it can tightly welded on the drill bits. The balance of the hardness and bending strength is very important for the wedge carbide buttons, so different formation we developed corresponding carbide grade to match it. Tungsten carbide buttons is widely used in petrol drilling, it also can be tools for tunneling, quarrying, mining and construction.
Main Grade list
It is very important to select the right grade to match the using purpose, we can offer experienced advice by considering the physical properties of the processing object, as well as the working condition for tools.
