Frictional kelly bar doesn't need to unlock the joint of its inner and outer lining so that it is convenient and fast to lift the bar. Non-stair key, friction transmission and the outside key are made by highly wear-resisting tempering steel. Friction Kelly Bar is applicable for layer of soft ground and mud, (mud) sand, gravel.
Interlocking kelly bar is of great pressure transmission and good anti-contortion perfomance. There are 3 rigid parts between drilling pipes to transfer greater pressure from embedding cylinder. And even at the hard geologic condition, it can transfer greater pressure and drill in. Stair key, organization transmission, the outside key are made by highly wear-resisting tempering steel. Interlocking Kelly Bar is applicable for soft fromations, (weak) weathered rock, hard strata construction.
