Drill tools are mainly used in geological drilling and mining operations to break rocks and soil. They are usually made of cemented carbide and have high wear resistance and strength.

In practical applications, suitable rotary digging teeth need to be selected according to the geological characteristics of the construction site to ensure construction efficiency and safety.

As a cutting tool on a rotary drilling rig, the digging teeth can cut and break geological materials such as soil and rock under the dual effects of rotation and advancement, thereby completing the excavation of pile foundation holes. Its design varies according to different operating environment and geological conditions, including shape, size, material and blade treatment, which need to be carefully considered to adapt to different formation conditions.
