Interlocking kelly bar
Interlocking Kelly bar contains two type pressure modes: one type is 3 or 6 external keys with 3 or more concave pressure parts, the other is 3 external pressure strips with full pressure parts on it, which mostly matched IMT drilling rig. and the advantage of transfer pressure easily and better anti-torque capacity. It’s suitable for both like dense sand and gravel or weak to strong rock.

Friction kelly bar
Friction Kelly bar is composed 3 or 6 wear-resistant seamless alloy strips by working through friction produced by rotary passing down the pressure force without concave pressure point. This type is suitable for both soft layer and silt layer.
