Abstract
An example whipstock assembly includes a whipstock providing a ramped surface and a longitudinal groove defined in the ramped surface. A lead mill is coupled to the whipstock with a shear bolt and having a slot defined therein, and a torque key is movable between an extended position, where the torque key is partially positioned within both the slot and the longitudinal groove, and a retracted position, where the torque key retracts into the slot. When the torque key is in the extended position, the torque key prevents the lead mill from rotating with respect to the whipstock.
