Cemented carbide buttons are mainly divided into several categories

       Do you know the main categories of cemented carbide buttons? What is the purpose?

Carbide spherical teeth: used to inlay rock drilling percussion bits, down-the-hole bits and roller cone bits for oil drilling rigs, suitable for very hard rock formations.



Carbide conical teeth: used to inlay rock drilling percussion bits, down-the-hole bits and roller cone bits for oil drilling rigs, suitable for medium-hard rock formations.



Warhead (parabolic) teeth: used to inlay down-the-hole drill bits and roller cone bits, suitable for hard rock formations.



Flat top gear: suitable for roller cone bits, diamond bits, hole stabilizers, etc., to reduce surface wear of steel trousers.



Spoon-shaped teeth: used to inlay roller cone bits, suitable for high-speed drilling of soft rock formations.

Wedge-shaped teeth: used to inlay special-shaped DTH drill bits and roller cone bits, suitable for soft rock formations with high drilling speed and low tooth fracture.
