Advantages of The Kelly Bar

Simple Structure

Friction-type drill pipe is a type of drill pipe whose external keys consist of three or six wear-resistant straight bars without large concave pressure platforms.

High Stability

This drill pipe generates pressure through the circumferential force produced during rotation and the friction created when the drill head applies downward force.

Easy to Operate

It is simple to operate, allows for deep drilling, and is suitable for soft soil or sandy silt layers.

Torsional Strength

This drill pipe transmits high pressure to the drilling tool, has strong torque resistance, and is suitable for drilling in harder formations.
