The purpose is to interlock each telescopic element to the inner following one in order to apply the maximum torque and crowd force developed by the base rig.Therefore the rotary table inner drive is also equipped with locking pockets,. When extracting the locking bar from down the hole, the combination of lifting and rotating counterclockwise will allow the telescopic element to unlock. interlocking Kelly bars are usually supplied with 3 or 4 telescopic elements.

Friction kelly bar derives its name from the means by which it transfer torque to the drilling tool. The telescopic elements are advanced by using the [frictional contact" from each of the friction drive rails that run down the outside of each kelly bar. These drive rails, on the outside of each kelly bar, are driven by the rotary table and the terminal joints of each successively larger diameter kelly bar. The terminal joint is long piece on the inside and at the bottom of each kelly bar. Friction kelly bars are normally supplied in 4 or 5 telescopic elements as they are mostly used for deep piles in medium hard soil conditions.
