Abstract
A well tool for drilling in, cementing and completing a liner installation in a single placement. A hydraulic setting tool actuates an adapter sleeve to decouple splines forming a two-direction torque drive. The hydraulic setting tool also actuates a slips set for hanging the liner and a deformable sleeve seal. A coupling includes external splines on the hydraulic setting tool and on the upper portion of the liner. Reverse threads engage the setting tool with the upper end of the liner as well. Movement of the adapter sleeve which has internal splines releases the spline coupling such that after the well has been completed, the drill string can be rotated to release the liner.
