48R32 thread button bit raw materials: Super wear-resistant hard tungsten alloy is used as button, which is impact-resistant, highly wear-resistant and highly thermally stable.
The body of the trousers undergoes secondary enhanced heat treatment, which increases the wear resistance and impact resistance of the trousers by 2 times year-on-year. The matching error between the super-hard tungsten alloy and the trousers is smaller. The advanced head design is conducive to slag removal and heat dissipation.
The button drill bit uses different alloy (hemispherical button, ballistic button, parabolic button, etc.) According to different rock formation structures and hardness. HLDRILL can produce alloy button drill bits of different specifications and forms according to different needs of users.
