Abstract: An improved hole opener assembly for horizontal drilling is disclosed that is less prone to failure as a result of cone arm break out or pocket side wall fracture. The interface between the cone arm and the pocket employs a key and slot configuration with a tighter fit than between the arm and the pocket to reduce the stress on the pocket side wall during drilling.
