10 Leading kelly bar Factory in China

Dec 05, 2025

Introduction to Kelly Bar

A kelly bar is a crucial component in the construction and foundation engineering industry. It is a long, hollow steel bar that is used in rotary drilling rigs. The main function of a kelly bar is to transmit torque and axial force from the drilling rig to the drill bit. This allows the drill bit to penetrate the ground, whether it is soil, rock, or other geological formations. Kelly bars come in different types, such as friction kelly bars and telescopic kelly bars, each designed to meet specific drilling requirements. They are essential for various construction projects, including building foundations, bridge piers, and geothermal well drilling.
