Friction Kelly bar

$25,000.00

Friction Kelly bar is another type of kelly bar, which the external key is composed of 3 or 6 wear -resistant strips without lock recesses. This kelly bar can form pressure force when the kelly bar is rotary. can produce peripheral force and the rotary passing down the pressure force, can produce the friction force. This kelly bar has the advantage of operating sample, drilling deep, but with less pressure transmission
