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 providing one or more blades, and a bearing support is arranged within the longitudinal groove and provides opposing sidewalls that define a slot configured to receive one of the one or more blades and thereby prevent the lead mill from rotating with respect to the whipstock.
