OVERVIEW

Kelly Bar

Kelly bars, also known as drilling Kellys or drill pipe Kellys, are essential components of rotary drilling equipment used in the construction and mining industries. They are primarily used in the drilling of deep boreholes for various purposes, such as oil and gas exploration, water well drilling, and foundation piling. Kelly bars are an integral part of the rotary drilling rig and play a crucial role in transferring torque and power from the rig's rotary drive to the drilling tool, which is typically a drill bit or auger.
