Mineral Hard Alloy Tooth Types
Classified by the shape of Hard alloy teeth, they mainly include spherical teeth, conical teeth, bullet-shaped teeth, wedge-shaped teeth, wing-shaped teeth, spoon-shaped teeth, flat-head teeth, saw-shaped teeth, etc.​

Spherical Teeth​

Product Introduction: These are used for inserting into rock drilling impact bits, down-the-hole drills, and roller cone bits for petroleum drilling rigs. They crush rocks through the combined actions of impact and compression, and are suitable for hard to extremely hard rock formations.

Conical Teeth​

Product Introduction: These are used for inserting into rock drilling impact bits, down-the-hole drills, and roller cone bits. They crush rocks through the combined actions of impact and crushing, and are suitable for hard rock formations.

Wedge-shaped Teeth​

Product Introduction: These are used for inserting into special-type down-the-hole drills and roller cone bits. They crush rocks through the combined actions of cutting and impact, and are suitable for soft rock formations requiring high drilling speed and low probability of tooth breakage.
