Tungsten Carbide Button for Drilling

Drilling means that relevant tungsten carbide button should be tough and hard enough. According to the different types of rock formation and hardness, they can be divided into different grades, such as YG6, YG8, YG8C, YG11C, YG13C, YG15, etc. If the rock formation is pretty hard and the impact is huge, we should choose the carbides contain Co more and raw grains alloy. On the contrary, we should choose the little one.

Tungsten carbide button are bearing strength of pulling, bending, pressing, twisting and some cyclic stress when it is working. So they have to bear thousands and thousands of impacts and corrosion, which requires that the button on drilling bit distributes well-regulated in order to make bearing equally. When you use large-scale rock dill, the ball-shaped with double angle of chamfer is a better choice. On the contrary, cone and wedge is beneficial for prolong working life.
