Kelly bars can be divided into two main types: friction kelly bars and interlocking kelly bars. Friction kelly bars are named such due to the frictional contact created between the
rails of each element. Interlocking kelly bars, on the other hand, do not have frictional contact between the
rails of each element, but instead have drive ribs that are welded
with lock devices in order to transfer the maximum amount of torque
to each scope. Standard kelly bars are manufactured to be fully
lockable systems with a mechanical locking mechanism between each
element and the outer bar and rotary drive.
