The introduction of the tungsten carbide drilling bits
The carbide drilling bits are chosen from the high virgin raw material with submicron and average garin size. The carbide drilling bits have the strict tolerance extent control, which can reach +/-0.01mm. You can choose as per your project from YG6, YG8, YG11, YG15, which are all available. They have the following types such as the standard, conical, parabolic, ballistic and other customized types. The carbide drilling bits have the following physical performances, such as the high hardness, impact toughness, great mechanical and chemical stability.
The advantages of the tungsten carbide drilling bits
The tungsten carbide drilling bits have the high wear resistance and impact-resistance. The tungsten carbide drilling bits have the long drilling life, which means it is not necessary to repair and grean. Their high efficiency could be promoted sharply in penetration of the high medium hard eock formation. At the meantime, the labour intensity could be reduced. The rock formation is suitable.
