Best 10 kelly bar Manufacturers in the world

Nov 19, 2025

Introduction to Kelly Bar

A Kelly bar is a crucial component in the construction and drilling industry. It is a long, hollow steel pipe with a square or hexagonal cross - section, used in rotary drilling rigs. The Kelly bar transfers torque and axial force from the drilling rig's power head to the drill bit. It allows for the penetration of various soil and rock layers during the construction of foundations, such as for buildings, bridges, and other large - scale infrastructure projects. The design and quality of a Kelly bar can significantly affect the efficiency, safety, and performance of the drilling operation.
